The subdivision of ß adrenergic receptors (p-AR) into ß1-and ß2-AR has led to the development of pi-and ß2-antagonists and/or agonists which have been useful for the treatment of cardiovascular disease and asthma. The recent discovery of"atypical"receptors, later called ß3-AR, has led to the development of P3-AR agonists which may be potentially useful as antiobesity and antidiabetic agents. For recent reviews on ß2-AR agonists, see: 1.

Compounds that are potent and selective ß3 agonists, may be potentially useful antiobesity agents. Low levels or lack of fil and ß2-agonistic properties will minimize or eliminate the adverse side effects that are associated with ß1 and ß2 agonistic activities, i. e. increased heart rate, and muscle tremor, respectively.

Early developments in the ps-agonist field are described in European patent 427480, US patents 4396627,4478849,4999377,5153210. Although the early developments purport to claim compounds with greater ß3-AR selectivity over the pi-and 2-AR. However, clinical trials in humans with those early developed (33-agonists have, so far, not been successful.

More recently, potent and selective human ß3 agonists have been described in several patents and published applications : WO 98/32753, WO 97/46556, WO 97/37646, WO 97/15549, WO 97/25311, WO 96/16938, WO 95/29159, European Patents 659737,801060,

714883,764640,827746, and US Patents 5561142,5705515,5436257, and 5578620. These compounds were evaluated in Chinese hamster ovary (CHO) cells test procedures, expressing cloned human ß3 receptors, which predict the effects that can be expected in humans (Granneman et al., Mol Pharmacol., 1992,42,964; Emorine et al., Science, 1989,245,1118; Liggett Mol. Pharmacol., 1992,42,634).

ß3-Adrenergic agonists also are useful in controlling the frequent urge of urination. It has been known that relaxation of the bladder detrusor is under beta adrenergic control (Li JH, Yasay GD and Kau ST Pharmacology 1992; 44: 13-18). Beta-adrenoceptor subtypes are in the detrusor of guinea-pig urinary bladder. Recently, a number of laboratories have provided experimental evidence of ß3 adrenergic receptors in a number of animal species including human (Yamazaki Y, Takeda H, Akahane M, Igawa Y, et al. Br. J. Pharmacol. 1998; 124: 593- 599), and that activation of the [33 receptor subtype by norepinephrine is responsible for relaxation of the urinary bladder.

Urge urinary incontinence is characterized by abnormal spontaneous bladder contractions that can be unrelated to bladder urine volume. Urge urinary incontinence is often referred to hyperactive or unstable bladder. Several etiologies exist and fall into two major categories, myogenic and neurogenic. The myogenic bladder is usually associated with detrusor hypertrophy secondary to bladder outlet obstruction, or with chronic urinary tract infection. Neurogenic bladders are associated with an uninhibited micturition reflex. An upper motor neuron disease is usually the underlying cause. In either case, the disease is characterized my abnormal spontaneous contractions that result in an abnormal sense of urinary urgency and involuntary urine loss. At present, the most common therapy for hyperactive bladder includes the use of antimuscarinic agents to block the action of the excitatory neurotransmitter acetylcholine. While effective in neurogenic bladders, their utility in myogenic bladders is questionable. In addition, due to severe dry mouth side-effects associated with antimuscarinic therapy, the patient compliance with these agents is only approximately 30%.

In the bladder, ß3 adrenergic receptor agonists activate adenylyl cyclase and generate cAMP through the G-protein coupled ps receptor. The resulting phosphorylation of phospho- lamban/calcium ATPase enhances uptake of calcium into the sarcoplasmic reticulum. The decrease in intracellular calcium inhibits bladder smooth muscle contractility.

It is suggested therefore, that activation of the ß3 adrenergic receptor in the urinary bladder will inhibit abnormal spontaneous bladder contractions and be useful for the treatment of bladder hyperactivity. Note, that unlike the antimuscarinics, ß3 adrenergic receptor agonists would be expected to be active against both neurogenic and myogenic etiologies.

Despite all these recent developments there is still no single therapy available for the treatment of type 11 diabetes (NIDDM), obesity, atherosclerosis, gastrointestinal disorders, neurogenetic inflammation, frequent urination and related diseases. A potent and selective ß3 adrenergic receptor agonist is therefore highly desirable for the potential treatment of such disease states.

This invention also provides processes for preparing the compounds of formula I which comprises one of the following: a) reacting a substituted (2S)-aryloxymethyl-oxirane of formula 11 wherein R is defined in relation to formula 1, with an appropriately 1-substituted-4- (aminomethyl)-piperidine of formula III : wherein Z and Ri are as defined in relation to formula I and Ris = H or trimethylsilyl to give a compound of formula I wherein A is-0-CH2- ;

b) reductive amination of substituted (2R)-hydroxyethylamines of formula V: wherein R and A are as defined in relation to formula 1, with an appropriate (1-substituted- piperidin-4-ylmethyl)-carboxaldehydes of formula VI wherein Ri and Z are defined in relation to formula 1, to give a compound of formula ! ; c) reacting a resin bound imine of formula XVI wherein = polystyrene and Ri is as defined herein, with a compound of formula V wherein A and R are as defined herein to give a compound of formula I where Z = S02 ; or d) removing any protecting groups from a compound of formula I in which at least one substituent carries a protecting group to give a compound of formula ; or e) converting a basic compound of formula I to a salt thereof by reaction with a pharmaceutical acceptable acid or f) converting a compound of formula I having one or more reactive substituent groups to a different compound of formula) ; or g) isolating an isomer of a compound of formula I from a mixture thereof.

The compounds of this invention may be prepared according to the following schemes from commercially available starting materials or starting materials which can be prepared using literature procedures. Reactive substituent groups may require protection during any

reaction and may be removed thereafter. These schemes show the preparation of representative compounds of this invention.

The compounds of formula I of the present invention where A = OCH2 can be prepared by the regiospecific ring opening of a substituted (2S)-aryloxymethyl-oxirane of formula 11 wherein R is defined in relation to formula I with an appropriately 1-substituted-4-(aminomethyl)-piperidine of formula III. where R, is defined in relation to formula I and R15 = H or trimethylsilyl.

When Pis = H, ring opening of the chiral epoxide to give the (3-amino alcohol was carried out using conditions similar to those described by Klunder et al., JOC, (1989), 54,1295. Thus, a mixture of 1 equivalent of the compounds of formula 11 and an excess of the compounds of formula III are heated as a solution in methanol at 60 °C for 16-24 hours to provide the chiral p-amino alcohols of formula 1.

For the case when R15= trimethylsilyl (TMS), the initially prepared free amine of formula II can be functionalized to the TMS analog as described in R. K. Atkins et al, Tet Lett, (1986), 27,2451. The TMS analog can then be coupled with 1 equivalent of a compound of formula 11 as described above.

In the case of compounds of formula 11 where R= 4-hydroxyphenyl, a mixture of 4- protected-oxy-phenoxymethyloxirane and an excess of the compounds of formula III are coupled to form intermediates of formula IV using the procedures stated above. wherein P = benzyl or t-butyldiphenylsilyl.

When P = benzyl, deprotection to the phenol is accomplished by hydrogenation over 10% palladium on carbon using either hydrogen gas, or catalytic hydride transfer with cyclohexene or ammonium formate.

When P = tert-butyldiphenylsilyl, deprotection to the phenol is accomplished by treatment of the tert-butyldiphenylsilyl intermediates of formula IV with 1 M tetrabutylammonium fluoride (TBAF) as described by Corey et al., JACS (1970), 94.6190), in tetrahydrofuran (THF) to give compounds of formula I where R4 = OH. The silyl protecting group may also be removed by treatment with hydrochloric acid as a solution in a solvent such as dioxane or by other suitable methods known to those skilled in the art.

Alternatively, compounds of formula I of the present invention can be prepared by reductive amination of substituted (2R)-hydroxyethylamines of formula V by the method of Borch, RF et al, JACS (1971), 93,2897 wherein R and A are as defined in relation to formula 1, with appropriately (1-substituted- piperidin-4-ylmethyl)-carboxaldehydes of formula Vi Thus, a solution of compounds of formula V and formula Vl is stirred in the presence of 1 equivalent of acetic acid in a suitable solvent such as methanol to form the intermediate imine which is reduced to the substituted 2-aryl-2-(R)-hydroxy-1-(piperidin-4-yl-methyl)- ethylamin compounds of the present invention with a hydride source such as sodium cyanoborohydride.

Compounds of formula 11 can be conveniently prepared as outlined in Scheme 1.

Scheme 1 a.) (S)-glycidyl nosylate, K2CO3, 2-butanone (MEK) reflux or b.) (R)-glycidol, diethylazodicarboxylate (DEAD), triphenylphosphine

A mixture of a hydroxyaryl compound, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, and (S)-glycidyl nosylate is heated at reflux for at least 18 hours in an appropriate solvent such as 2-butanone (MEK) in the presence of a suitable base such as potassium carbonate to provide compounds of formula 11.

Alternatively, compounds of formula 11 can be prepared from dropwise treatment of a solution of the hydroxyaryl compound, R (+)-glycidol and triphenylphosphine in dry THF with 1.1 eq. of diethylazodicarboxylate as described by O. Mitsinobu., Bull Soc. Chem Jap., (1967), 60, 2380.

Compounds of formula III can be conveniently prepared via Scheme 2.

Scheme 2 a.) RiZ-halo, base b.) LAH or BH3-THF Thus, when R1= alkyl, hydroxyalkyl and Z= bond, reaction of commercially available isonipecotamide with an alkyl iodide (or bromide), either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, in an appropriate solvent such as MEK and base such as potassium carbonate provides the intermediate carboxamides. The carbonyl can then be reduced conveniently to the desired 1-substituted-4-aminomethyl-piperidine with lithium aluminum hydride (LAH) in a solvent such as THF to give compounds of formula Ill.

The above procedure is also used for the case where R, = heteroaryl and Z = bond from reaction of isonipecotamide in an analogous fashion with chloro or bromo substituted heterocycles, either available commercially or are known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds.

Where Ri is defined in relation to formula I and Z = SO2, reaction of isonipecotamide with a substituted sulfonyl chloride, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, in a solvent such as THF, dioxane or methylene chloride with an acid scavenger such as

diisopropylethyl amine or other hindered organic base provides the intermediate 4- carboxamido-l-piperidinyl-substituted sulfonamides. Selective reduction of the amide carbonyl to the desired 4-aminomethyl-1-piperidinyl-substituted sulfonamides can be accomplished using a suitable reducing agent such as BH3-THF complex in THF to give compounds of formula III as described by Green et al., Tetrahedron (1995), 51,2865.

Where Ri is defined in relation to formula I and Z= (C=O), reaction of isonipecotamide with a substituted isocyanate, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, in a solvent such as THF, dioxane, ethanol, methanol or methylene chloride provides the intermediate 1- (4-carboxamido-piperidin-1-yl)-3-substituted urea. Reduction of the amide carbonyl to the desired 1- (4-aminomethyl-piperidin-1-yl)-3-substituted urea can be accomplished using a suitable reducing agent such as BH3-THF complex in THF to give compounds of formula lil.

Alternatively, the urea formation can be accomplished by first treating isonipecotamide with 0.33 equivalents of triphosgene dropwise over at least 1 hour in the presence of an acid scavenger such as diisopropylethyl amine. The other amine of choice is added in one portion to complete the urea formation.

Compounds of formula III may also be prepared from piperidin-4-ylmethyl-carbamic acid t-butyl ester as outlined in Scheme 3.

Scheme 3 a.) LAH, THF b.) Boc2O, K2CO3 c.) H2, 10% Pd/C d.) R1Z-halo, base e.) formic acid or TFA Thus, in the case where R1 is defined in relation to formula I and Z = SO2, reaction of piperidin-4-ylmethyl-carbamic acid t-butyl ester with a substituted sulfonyl chloride, either available commercially or is known in the art, or can be prepared by procedures analogous to

those in the literature for the known compounds, in a solvent such as THF, dioxane or methylene chloride with an acid scavenger such as diisopropylethyl amine or other organic base. Several methods available for deprotection of the carbamate (Boc) are known (see Greene T.,"Protective Groups in Organic Synthesis", Wiley Interscience) to one skilled in the art. The preferred method used was treatment with neat formic acid or neat trifluoroacetic acid (TFA) to give sulfonamides of formula 111.

Piperidin-4-ylmethyl-carbamic acid t-butyl ester is prepared as shown in Scheme 3 from reduction of 1-benzyl-isonipecotamide with LAH followed by Boc protection of the primary amine by treatment with di-t-butyidicarbonate in a suitable solvent such as dioxane-water in the presence of potassium carbonate.

Similarly compounds of formula VI where Ri is defined in relation to formula I and Z = SO2, may be prepared from 4-formylpiperidine dimethyl acetal as outlined in Scheme 4: Scheme 4 a.) PCC, CH2CI2 b.) HC (OCH3) 3 p-tosH c.) cyclohexene, 10% Pd/C d.) RIZ-halo, base e.) formic acid or TFA Thus, reaction of 4-formylpiperidine dimethyl acetal with a substituted sulfonyl chloride, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, in a solvent such as THF, dioxane or methylene chloride with an acid scavenger such as diisopropylethyl amine or other organic base followed by deprotection of the aldehyde with neat formic acid or neat TFA affords sulfonamides of formula VI. Deprotection may also be accomplished by treatment with trichloromethylsilane and sodium iodide in acetonitrile at ambient temperature using a procedure described by G. Olah et al, JOC (1983), 48, 3667.

4-Formylpiperidine dimethyl acetal is prepared as outlined in Scheme 4. Thus, 4- hydroxymethyl-1-piperidinyl carbamic acid benzyl ester is oxidized with pyridinium

chlorochromate to the aldehyde which is protected as the dimethyl acetal by reaction with a large excess of trimethyl orthoformate in the presence of a catalytic amount of p-toluene- sulfonic acid in a suitable solvent such as methanol.

Compounds of formula III and formula VI where Z = SO2, R1= analogs of the type

and where R8 and R12 are defined in relation to formula 1, can be conveniently prepared from the intermediates of formula Vill. where

The intermediate of formula Vlil, where R16 is the carboxamido derivative, can be converted to compounds of formula Vil by reaction with reactive substituted isocyanates, either available commercially or are known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, to provide the urea. The carboxamide can be reduced with borane-THF as described above to the 1- [4- (4-aminomethyl-1-piperidinyl)- benzenesulfonyl]-3-substituted urea of formula Vil.

The intermediate of formula Vill, where R16 is the Boc-aminomethyl moiety can be converted to ureas of formula VII by reaction of [1- (4-Aminobenzenesulfonyl)-piperidin-4- ylmethyl]-carbamic acid t-butyl ester with 0.33 equivalents of triphosgene in the presence of an acid scavenger such as triethyl amine in an appropriate solvent such as THF or methylene chloride followed by a primary amine, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds.

Alternatively a secondary amine can be used which is either available commercially, known in the art or can be prepared by procedures analogous to those in the literature for the known

compounds. In the present invention these secondary amines are prepared by reaction of carboxylic acids activated by carbonyidiimidazole with primary amines described above in the presence of an organic base such as diisopropylethyl amine. Deprotection of the intermediate [1- (4-substituted ureido-benzenesulfonyl)-piperidin-4-ylmethyl]-carbamic acid t-butyl ester is carried out with formic acid or TFA as described above to give compounds of formula Vil.

Alternatively, [1- (4-Aminobenzenesulfonyl)-piperidin-4-ylmethyl]-carbamic acid t-butyl ester can be derivatized to the urea by reaction with an isocyanate derived via Curtius rearrangement of an intermediate acyl azide, prepared by reaction of a carboxylic acid, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, with diphenylphosphoryl azide in the presence of an acid scavenger such as triethyl amine (Shioiri, T. et al., J. Amer. Chem. Soc. (1972), 94, 6203-5).

Alternatively, The intermediate of formula Viol, where R16 is the 4-formyl-dimethyl acetal moiety can be converted to ureas of formula Vil via the urea forming reactions presented above. Deprotection of the of the intermediate [1- (4-substituted ureido-benzenesulfonyl)- piperidin-4-yl]-carboxaldehyde dimethyl acetal is carried out with formic acid or TFA as described above to give compounds of formula VII.

Compounds of formula III and formula VI where Z= S02 and R1 = amide analogs of the type IX where R12 = alkyl, arylalkyl, heteroaryl, can also be prepared from the reaction of the intermediates of Vil with an acid chloride prepared from a carboxylic acid, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the preparation of activated esters commonly used in peptide synthesis (see M. Bodanszky and A. Bodansky"The Practice of Peptide Synthesis", Springer-Verlag Berlin Heidelberg New York Tokyo, 1984) and known to those skilled in the art. Following deprotection or reduction as previously described provides compounds of the formula IX Compounds of formula Vlil can be prepared as outlined in scheme 2, scheme 3 or scheme 4 by reaction of 4-nitrobenzene sulfonyl chloride with either isonipecotamide or (piperidin-4-ylmethyl)-carbamic acid t-butyl ester or 4-formylpiperidine dimethyl acetal in

methylene chloride or THF in the presence of a suitable acid scavenger such as diisopropyl amine. The nitro can be reduced to the amine by hydrogenation at atmospheric pressure in ethanol over 10% palladium on carbon or by a variety of other methods known to those skilled in the art.

Alternatively, the compound of formula VIII where Rie = Boc-aminomethyl, can be prepared from 4-aminomethylpiperidine according to the procedure outlined by J. D. Prugh et. al. Synth Comm, 22,2357 (1992). A solution of benzaldehyde and 4-aminomethylpiperidine in toluene is heated at reflux until 1 equivalent of water was collected in a Dean-Stark trap. To the cooled reaction mixture is added 4-nitro-benzenesulfonyl chloride and a suitable acid scavenger such as diisopropylethyl amine. The intermediate coupled imine is decomposed by the addition of mild inorganic acid such as dilute HCI.. Protection of the amine can be accomplished by treatment with ditertbutyidicarbonate in a suitable solvent system such as THF or dioxane-water.

Compounds of formula))) and formula VI where Z = SO2, Ri= compounds of the formula

and Rg is heteroaryl, can be prepared from the intermediates of formula XI where

Ris= F, CN, or heterocycle For compounds of formula XI where R17 is the methyl-carbamic acid t-butyl ester moiety or dimethyl acetal and Ris is F, an anion of a heterocycle is coupled with an arylfluoro compound as described by Caubere, P. et al., Bull. Soc. Chim. Fr. (1969), Issue 8,2854-63. Thus a solution of [1- (4-fluorobenzenesulfonyl)-piperidin-4-ylmethyl]-carbamic acid t-butyl ester or [1- (4-fluorobenzenesulfonyl)-piperidin-4-yi]-carboxaldehyde dimethyl acetal with an

anion derived from potassium hydride of a nitrogen containing heterocycle, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, in a suitable solvent such as DMF is maintained at 80°C to 100°C for at least 18 hours, followed by deprotection of the Boc or acetal groups as described above to give compounds of formula X.

For compounds of formula Xi where R17 is the methyl-carbamic acid t-butyl ester moiety or dimethyl acetal and Ris is CN, oxadiazoles of formula X can be prepared by a method descibed by Hussein A. Q.,. Heterocycles, (1987), 26,163. Thus the cyano is functionalized by reaction with ammonium hydroxide hydrochloride in the presence of potassium carbonate in a suitable solvent such as ethanol to give the intermediate amino (hydroxyimino) methyl compound. The intermediate is coupled with acid chlorides either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, in the presence of a suitable base such as pyridine followed by deprotection of the Boc or acetal groups as described above to give compounds of formula X where Rg = 5-substituted oxadiazoles.

Compounds of formula XI where R17 is the methyl-carbamic acid t-butyl ester moiety or dimethyl acetal and R18 = heterocycles such as imidazol-2-ones can also prepared by the method described by Poindexter et al., JOC, (1992), 57,6257. Thus, heating a mixture of aniline hydrochloride and a 2-substituted oxazolidinone at temperatures of at least 180°C for a period of at least 2 hours affords the intermediate phenylethylene diamine. The imidazolone is formed by reaction of this intermediate with triphosgene in the presence of a suitable base such as triethyl amine to give the intermediate 1-phenyl-3-substituted-imidazol-2-one.

Sulfochlorination with chlorosulfonic acid provides the intermediate 4- (3-substituted-2-oxo- imidazolidin-1-yl)-benzenesulfonyl chloride which can be converted to compounds of formula XI by reaction with either piperidin-4-ylmethyl-carbamic acid t-butyl ester or 4-formylpiperidine dimethyl acetal using methodology described previously.

The intermediates of formula XI are prepared by coupling 4-fluorobenzensulfonyl chloride with (piperidin-4-ylmethyl)-carbamic acid t-butyl ester or 4-formylpiperidine dimethyl acetal in DMF in the presence of a suitable acid scavenger such as such as potassium carbonate at 100°C for a period of at least 18 hours.

Compounds of formula III and formula vol where Z= bond, Ri =compounds of the following type

wherein B= CH or N and R19 = NHR12, NHCH (COOR8) R12 or NHCH (COOH) Ri2 can be prepared via intermediate Bill : where

by standard peptide coupling reactions such as coupling an amine or amino acid ester, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, with an activated ester of Vil prepared from benzyltriazol-1-yloxytris (dimethylamino)-phosphonium hexafluorophosphate and an organic base like triethyl amine in a solvent such as DMF. Alternatively an activated ester of Xiil may be prepared with 1- (3-dimethylamino-propyl)-3-ethylcarbodiimide HCI and 1- hydroxybenzotriazole in the presence of an organic base such as N-ethyl morpholine in a solvent such as THF.

Compounds of formula V can be prepared via mono-chlorination of intermediates of the formula XIV wherein R is defined as in formula I by a procedure outlined by Kajigaeshi et al, Synthesis (1988), 546. Thus the appropriate acetyl compound, either available commercially or is known in the art, or can be prepared by procedures analogous to those in the literature for the known compounds, is treated with benzyltrimethylammonium tetrachloroiodate in a solution of methylene chloride to give a high yield of the mono-chloro product which can be purified by crystallization.

The mono-chloro product is chirally reduced to the intermediate XV

with borane-THF and a chiral auxilary agent such as (R)-tetrahydro-1-methyl-3, 3-diphenyl-1 H, 3H-pyrrolo [1,2-c] [1,3,2] oxazaborole as described by Gorey, E. J. et al., J. Org. Chem, (1991), 56,442.

Subsequent reaction of the intermediate XI with sodium azide and an excess of sodium iodide in dimethylsulfoxide (DMSO) at 40°C to 60°C for 24 to 168 hours followed by reduction of the intermediate azide with hydrogen at 45 PSI over 10 % palladium on carbon provides the compounds of formula Vill.

Alternatively, compounds of formula I where Z = S02 can be prepared in simultaneous fashion using a technique known as"solution phase parallel synthesis"as described by Balkenhohl in Angew. Chem. Int. Ed. Engl., 1996,35,2288-2337. In this procedure two or more reaction products are simultaneously prepared in separate vessels. The number of reaction vessels being equal to the number of expected products. The ease of solution phase parallel synthesis is aided through the addition of"resin bound reagents"to the reaction mixture which can be filtered through glass or polypropylene frits or other filtration methods known to those skilled in the art. Resin bound reagents are chemicals that are attached to polymeric materials, such as polystyrene, typically through covalent or ionic chemical bonds, and can assist in the reaction process itself or scavenge side products/excess starting materials from a reaction mixture. At the conclusion of the reaction the resin bound reagents are filtered from the reaction medium to provide a highly purified product which may now be obtained through solvent evaporation of the filtrate. = polystyrene (XVI According to the description above compounds of formula I where Z = SO2 can be prepared from resin bound imines of formula XVI by suspending the resin in a suitable, anhydrous solvent mixture such as 50: 50 methanol-trimethylorthoformate (TMOF), distributing the resin suspension to separate vessels, adding a different amine of type V as the limiting reagent and resin bound reducing agent, such as borohydride on resin, to each vessel. The mixtures can be shaken 1-48 hours and then filtered. The filtrate can then be evaporated to obtain products.

XVII XVI Resin bound imines of the type XVI can be prepared as described by Look in Tetrahedron Lett., 1995,36,2937-2940 by suspending a resin bound primary amine, either commercially available or available through literature procedures, treating the suspension with an aldehyde of the type XVII and removal of water by physical or chemical means. Typically, water is removed by chemical means through the use of trimethylorthoformate as the primary solvent. After 1-48 hours of agitation the suspension is filtered to obtain the resin bound imine as the residue. The filtration step also removes unreactive impurities in the aldehyde from the product resin. For example, a mixture of an aldehyde and an alcohol are reacted with aminomethyl resin and filtered. The filtrate contains alcohol impurity only while none of the impurity resides on the resin. Cor03 HO H 2 1 1, 2-dichloroethane XVIII XVIi Aldehyde of the type XVII are prepared by oxidation of corresponding sulfonamide alcohols of the type XVIII. In particular the alcohols are oxidized with resin bound chromium trioxide in 1,2-dichloroethane according to the method of Cainelli as described in J. Am. Chem.

Soc., 1976,98,6737-6738. Filtration of the reaction suspension and evaporation of the solvent leads to the isolation of aldehydes XVII contaminated with up to 25% of the starting sulfonamide alcohol XVIII.

Sulfonamide alcohols of the type XVIII can be prepared according to the procedure of Flynn as described in J. Am. Chem. Soc., 1997, 19, 4874-4881 by reacting an excess of the sulfonyl chloride (table 1 or 2) with 4- (hydroxymethyl) piperidine XIX in an appropriate solvent such as dichloromethane. Addition of an insoluble resin bound tertiary amine such as morpholinomethylpolystyrene reacts with and retains hydrogen chloride byproduct on the insoluble resin. After an appropriate reaction time of 1-48 hours a primary or secondary amine resin such as aminomethylpolystyrene can be added to react with the excess sulfonyl chloride which will retain the excess starting material on the insoluble resin. Filtration of the resulting suspension and evaporation of the solvent provides pure product that is free of byproducts and unreacted starting materials.

The compounds of this invention are useful in treating metabolic disorders related to insulin resistance or hyperglycemia, typically associated with obesity or glucose intolerance.

The compounds of this invention are therefore, particularly useful in the treatment or inhibition of type 11 diabetes. The compounds of this invention are also useful in modulating glucose levels in disorders such as type I diabetes.

The ability of compounds of this invention to treat or inhibit disorders related to insulin resistance or hyperglycemia was confirmed with representative compounds of this invention in the following standard pharmacological test procedures, which measured the binding selectivity to the ß1,ß2, and ß3 adrenergic receptors. Binding to the receptors was measured in Chinese Hamster ovary (CHO) cells that were transfected with adrenergic receptors. The following briefly summarizes the procedures used and results obtained.

Transfection of CHO cells with 31 and P2 adrenergic receptors: CHO cells were transfected with human (31-or 2-adrenergic receptors as described in Tate, K. M.,, Eur. J.

Biochem., 196:357-361 (1991).

Cloning of Human (33-AR Genomic DNA: cDNA was constructed by ligating four polymerase chain reaction (PCR) products using the following primers: an ATG-Narl fragment, sense primer 5'-CTTCCCTACCGCCCCACGCGCGATC3'and anti-sense primer 5'CTGGCGCCCAACGGCCAGTGGCCAGTC3' ; a Narl-Accl fragment, 5'TTGGCGCTGATGGCCACTGGCCGTTTG3'as sense and 5'GCGCGTAGACGAAGAGCATCACGAG3'as anti-sense primer; an Accli-Styl fragment, sense primer 5'CTCGTGATGCTCTTCGTCTCACGCGC3'and anti-sense primer

5'GTGAAGGTGCCCATGATGAGACCCAAGG3'and a Styl-TAG fragment, with sense primer 5'CCCTGTGCACCTTGGGTCTCATCATGG3'and anti-sense primer 5'CCTCTGCCCCGGTTACCTACCC3'. The corresponding primer sequences are described in Mantzoros, C. S., etal., Diabetes 45 : 909-914 (1996). The four fragments are ligated into a pUC 18 plasmid (Gibco-BRL) and sequenced. Full length 03 AR clones (402 amino acids) containing the last 6 amino acids of hp3-AR are prepared with the ß3-ßARpcDNA3 from ATTC.

Binding Procedure: Clones expressing receptor levels of 70 to 110 fmoles/mg protein were used in the test procedures. CHO cells were grown in 24-well tissue culture plates in Dulbecco's Modified Eagle Media with 10% fetal bovine serum, MEM non-essential amino acids, Penicillin-Streptompycin and Geneticin. On the day of test procedure, growth medium was replaced with preincubation media (Dulbecco's Modified Eagle Media and incubated for 30 minutes at 37° C. Preincubation medium was replaced with 0.2 ml treatment medium containing DMEM media containing 250 I1M IBMX (isobutyl-1-methylxantine) plus 1 mM ascorbic acid with test compound dissolved in DMSO. Test compounds were tested over a concentration range of 10-9 M to 10-5 M for ß3 cells and 10-8 to 10-4 M for ß1 and ß2 transfected cells. Isoproterenol (10-5 M) was used as an internal standard for comparison of activity. Cells were incubated at 37° C. on a rocker for 30 min with the pg cells and 15 min for ß1 and P2 cells. Incubation was stopped with the addition of 0.2N HCI and neutralized with 2.5N NaOH. The plates, containing the cells and neutralized media, were stored at-20 degrees celsius until ready to test for cAMP using the SPA test kit (Amersham).

Data Analysis and Results: Data collected from the SPA test procedure were analyzed as per cent of the maximal isoproterenol response at 10-5 M. Activity curves were plotted using the SAS statistical and graphics software. EC50 values were generated for each compound and the maximal response (IA) developed for each compound is compared to the maximal response of isoproternol at 10-5 M from the following formula: IA = % activity compound % activity isoproterenol.

Table I shows the ß3-adronergic receptor EC50 and IA values for the representative compounds of this invention that were evaluated in this standard pharmacological test procedure. These results show that compounds of the present invention have activity at the ß3-adrenergic receptor. The compounds of this inventon had weaker or no activity at ßl and/or ß2-adrenergic receptor.

Evaluation in ß3 Knockout (KO) and p3 Transgenic (Tg) Mice: The ability of compounds of this invention to treat or inhibit disorders related to insulin resistance or hyperglycemia was also confirmed with representative compounds of this invention in an in vivo standard pharmacological test procedure which compared thermogenesis in transgenic mice (Tg mice) and (33-knockout mice (KO mice). The procedure used and results obtained are provided below.

ß3-Adrenergic receptor knockout mice and ß3 human transgenic mice are created on an inbred FVB background (Susulic, V. S., et. al., J. Biol. Chem., 1995,270 (49), 29483-29492).

Female FVB ß3 transgenic and ß3 knockout mice were used to determine in vivo activity and selectivity of ß3 agonists. Compounds selected for in vivo testing had ß3 EC5o<30 nm and were full agonists in CHO cells expressing human p3 receptors. These compounds were also selective in being 100-fold less responsive and partial agonists when tested in 31 and ß2 transfected CHO cells. Compounds were tested for increased thermogenesis using the Oxymax indirect calorimeter (Columbus Instruments, Columbus, Ohio). Fed animals were placed in chambers for 3 hours to obtain baseline 02 and C02 values. Eight fed mice were weighed in pairs and placed in 4 chambers, two per chamber. The relative gas content of each chamber was sampled and recorded at 10 to 12 minute intervals. For each sample, energy expenditure values were calculated by the Oxymax and expressed as kcal/hr. After 3 hours of baseline measurement, the mice were removed, treated and replaced in the chambers. The ß3 agonists were injected at doses between 0.1 and 20 mg/kg i. p. and between 1.0 and 30 mg/kg for oral administration. Compounds in 10 mM or 10 mg/ml DMSO solutions were suspended in 0.5% methylcellulose : 0.1% tween-80 and injected i. p. or administered by oral

gavage. Some compounds were suspended in 5.0% tween-80 for oral administration. Post- treatment kcal/hr values were taken between 40 minutes and 2.5 hours later. The 6 to 10 sample sections of the pre-treatment and post-treatment periods, which appear to best represent stable resting thermogenesis, were selected. Each of these sample values was corrected for body weight and used such that each pair of mice serves as its own baseline for both T test and percent increase in thermogenesis calculations. An ANOVA and a one sided T test (H1 : Post>Pre) are performed using the SAS software modified to down weight extreme values. In a separate set of calculations, values that appear to be too high to represent resting thermogenesis are discarded (activity monitor sampling associated spikes in thermogenesis with ambulatory activity). The mean baseline value for each chamber is subtracted from mean post-treatment value for that chamber. This baseline-subtracted value is divided by the mean baseline value and multiplied by 100 to obtain a percent increase in thermogenesis for each chamber. The combined mean percent increase, standard deviation, and standard error of the mean for each chamber is calculated. Compounds were considered active if they were able to produce a statistically significant 15% increase in thermogenesis in 33 transgenic mice and no significant increase in ß3 knockout mice. The results are shown in the table below.

Carriers suitable for use to make up the feed supplement compositions include the following : alfalfa meal, soybean meal, cottonseed oil meal, linseed oil meal, sodium chloride, corneal, cane molasses, urea, bone meal, corncob meal and the like. The carrier promotes a uniform distribution of the active ingredients in the finished feed into which the supplement is blended.

It thus performs an important function by ensuring proper distribution of the active ingredient throughout the feed. The supplement is used as a top dressing for the feed, it likewise helps to ensure uniformity of distribution of the active material across the top of the dressed feed.

The preferred medicated swine, cattle, sheep and goat feed generally contain from 0.01 to 400 grams of active ingredient per ton of feed, the optimum amount for these animals usually being about 50 to 300 grams per ton of feed. The preferred poultry and domestic pet feed usually contain about 0.01 to 400 grams and preferably 10 to 400 grams of active ingredient per ton of feed.

For parenteral administration the compounds of the present invention may be prepared in the form of a paste or a pellet and administered as an implant, usually under the skin of the head or ear of the animal in which increase in lean meat deposition and improvement in lean mean to fat ratio is sought. In general, parenteral administration involves injection of a sufficient amount of the compounds of the present invention to provide the animal with 0.001 to 100 mg/kg/day of body weight of the active ingredient. The preferred dosage for swine, cattle, sheep and goats is in the range of from 0.001 to 50 mg/kg/day of body weight of active ingredient; whereas, the preferred dose level for poultry and domestic pets is usually in the range of from 0.001 to 35 mg/kg/day of body weight.

Paste formulations can be prepared by dispersing the active compounds in a pharmaceutically acceptable oil such as peanut oil, sesame oil, corn oil or the like. Pellets

containing an effective amount of the compounds of the present invention can be prepared by admixing the compounds of the present invention with a diluent such as carbowax, carnuba wax, and the like, and a lubricant, such as magnesium or calcium stearate, can be added to improve the pelleting process. It is, of course, recognized that more than one pellet may be administered to an animal to achieve the desired dose level which will provide the increase in lean meat deposition and improvement in lean meat to fat ratio desired. Moreover, it has been found that implants may also be made periodically during the animal treatment period in order to maintain the proper drug level in the animal's body. For the poultry and swine raisers, using the method of the present invention yields leaner animals.

Additionally, the compounds of this invention are useful in increasing the lean mass to fat ratio in domestic pets, for the pet owner or veterinarian who wishes to increase leanness and trim unwanted fat from pet animals, the present invention provides the means by which this can be accomplished.

The following describe the preparation of representative examples of this invention.

EXAMPLES 116-183 To fourteen 20 mL screw cap vials was added 4-methylmorpholinepolystyrene (250 mg/vial, 3.6 mmol/g, 0.90 mmol) and a 0.11 M solution of 4-(hydroxymethyl) piperidine (4 mL, 0.45 mmol). The vials were agitated on an orbital shaker for 2 minutes then to each one was added 0.585 mmol of the corresponding sulfonyl chloride of R2 from Table 2 and capped tightly. After shaking for 1 h aminomethylpolystyrene (94 mg, 2.4 mmol/g, 0.225 mmol) was added to each vial and shaking continued for another 2 h. The mixtures were filtered into separate 20 mL vials, the residual resin was washed with dichloromethane (4 X 3 mL) and the filtrates were evaporated under a stream of nitrogen. Thin layer chromatography (silica gel, 50% hexane in ethyl acetate) indicated homogeneous products.

To each of the product vials from above was added polymer supported chromium trioxide (1.4 g, 2.5 mmol/g, 3.6 mmol) and 1,2-dichloroethane (5 mL). The vials were capped tightly and the mixtures shaken and heated at 75 °C for 14 h. After cooling to 20 °C the product mixtures were filtered, washed (DCM, 4 X 2 mL) and evaporated to dryness. To each vial was added aminomethylpolystyrene (0.28 g, 2.39 mmol/g, 0.675 mmol) and trimethylorthoformate (4 mL). After shaking for 1 h the resin was filtered, washed (DCM, 3 X 3 mL) and dried (hi-vac, 16 h).

Seventy polypropylene filter tubes (15 mL) were fitted with PTFE stopcocks and placed erect in a 5 (column) X 14 (row) parallel fashion. Each of the resin supported aldehyds above were divided into five equal batches of 43 mg (68, mol, approx.) and placed in the individual filter tubes by row so that each sample in each row contained an equal amount of identical resin. To each vessel in a single column of the parallel reaction mixture was added 54 gaol of an amine from table 3 such that a different amine was present in each column. To each reaction mixture was added methanol (0.75 mL) and trimethylorthoformate (0.75 mL). The block of seventy samples was then agitated on an orbital shaker for 1.5 h and stopped. To each vessel was added polymer supported borohydride and orbital shaking continued another 18 h. The mixtures were filtered into 20 mL scintillation vials, the resin was washed (methanol, 1 mL) and the filtrates were evaporated. The crude products were purified by automated reversed phase HPLC and the fractions were evaporated into 8 mL scintillation vials. All products were characterized by reversed phase analytical HPLC (stationary phase: C18, 4.4 mm X 5 cm ; mobile phase: 2-98% acetonitrile-water containing 0.05% TFA, linear gradient, 1.5 mL/min., 14 mins., 215 nM) and positive electrospray mass spec.
