1 H-PYRROLO[2,3-β]PYRIDINES

FIELD OF THE INVENTION

This invention relates to novel compounds, compositions containing them, their use as inhibitors of SGK-1 kinase, and their use in the treatment of diseases mediated at least in part by SGK-1 kinase.

BACKGROUND OF THE INVENTION

An important large family of enzymes is the protein kinase enzyme family. Currently, there are about 400 different known protein kinases. However, because three to four percent of the human genome is a code for the formation of protein kinases, there may be many thousands of distinct and separate kinases in the human body. Protein kinases serve to catalyze the phosphorylation of an amino acid side chain in various proteins by the transfer of the γ-phosphate of the ATP-Mg 2+ complex to said amino acid side chain. These enzymes control the majority of the signaling processes inside cells, thereby governing cell function, growth, differentiation and destruction (apoptosis) through reversible phosphorylation of the hydroxyl groups of serine, threonine and tyrosine residues in proteins. Studies have shown that protein kinases are key regulators of many cell functions, including signal transduction, transcriptional regulation, cell motility, and cell division. Several oncogenes have also been shown to encode protein kinases, suggesting that kinases play a role in oncogenesis. These processes are highly regulated, often by complex intermeshed pathways where each kinase will itself be regulated by one or more kinases. Consequently, aberrant or inappropriate protein kinase activity can contribute to the rise of disease states associated with such aberrant kinase activity. Due to their physiological relevance, variety and ubiquitousness, protein kinases have become one of the most important and widely studied family of enzymes in biochemical and medical research. The protein kinase family of enzymes is typically classified into two main subfamilies: Protein Tyrosine Kinases and Protein Serine/Threonine Kinases, based on the amino acid residue they phosphorylate. The serine/threonine kinases (PSTK), includes cyclic AMP- and cyclic GMP-dependent protein kinases, calcium and phospholipid dependent protein kinase, calcium- and calmodulin-dependent protein kinases, casein kinases, cell division cycle protein kinases and others. These kinases are usually cytoplasmic or associated with the particulate fractions of cells, possibly by anchoring proteins. Aberrant protein serine/threonine kinase activity has been implicated or is suspected in a number of pathologies such as rheumatoid arthritis, psoriasis, septic

shock, bone loss, many cancers and other proliferative diseases. Accordingly, serine/threonine kinases and the signal transduction pathways which they are part of are important targets for drug design. The tyrosine kinases phosphorylate tyrosine residues. Tyrosine kinases play an equally important role in cell regulation. These kinases include several receptors for molecules such as growth factors and hormones, including epidermal growth factor receptor, insulin receptor, platelet derived growth factor receptor and others. Studies have indicated that many tyrosine kinases are transmembrane proteins with their receptor domains located on the outside of the cell and their kinase domains on the inside. Much work is also under progress to identify modulators of tyrosine kinases as well.

Serum and Glucocorticoid-Regulated Kinase 1 (SGK-1) is a serine/threonine protein kinase, whose function is thought linked to cell proliferation and electrolyte homeostasis. SGK-1 is a member of a family of intracellular kinases which includes protein kinase B. While it is transcriptionally induced by glucocorticoids and mineralocorticoids, it is activated by insulin and IGF-1 mediated phosphorylation through PI3-kinase and PDK-1. SGK-1 is thought to mediate several mechanisms, which contribute to disease states. As indicated above, IGF-1 activates SGK-1 and is involved in fibronectin synthesis, an element of renal fibrosis. Consequently, SGK-1 may mediate IGF-1 action on fibronectin synthesis. The anti-diuretic aldosterone induces expression of SGK-1 , which in turn activates the epithelial Na+ channel thereby affecting Na+ transport. Accordingly, SGK-1 may serve to mediate aldosterone-induced Na+ retention in renal and cardiovascular disease. SGK-1 may also mediate repair processes involving cell proliferation, for instance, through thrombin. Thrombin causes renal cell proliferation and increases SGK-1 expression in renal cells. Therefore, SGK-1 may provide a novel therapy for the regulation of electrolyte balance in renal and cardiovascular disease and in damaging cell proliferation in renal disease.

The present inventors have discovered novel 1 H-pyrrolo[2,3-jb]pyridine compounds and/or methods for inhibition of SGK-1 kinase activity. The 1 H-pyrrolo[2,3-t)]pyridines described herein are useful in the treatment of disorders associated with SGK-1 activity.

Such derivatives are clear to those skilled in the art, without undue experimentation, and with reference to the teaching of Burger's Medicinal Chemistry and Drug Discovery, 5 th Edition, Vol. 1 : Principles and Practice, which is herein incorporated to the extent that it teaches physiologically functional derivatives.

As used herein, the term "optionally" means that the subsequently described event(s) may or may not occur, and includes both event(s), which occur, and events that do not occur.

As used herein, the term "solvate" refers to a complex of variable stoichiometry formed by a solute and a compound of this invention, or a salt or physiologically functional derivative thereof, and a solvent. Such solvents for the purpose of the invention may not interfere with the biological activity of the solute. Examples of suitable solvents include, but are not limited to, water, methanol, ethanol and acetic acid. Preferably the solvent

used is a pharmaceutically acceptable solvent. Examples of suitable pharmaceutically acceptable solvents include, without limitation, water, ethanol and acetic acid.

As used herein, the term "substituted" refers to substitution with the named substituent or substituents, multiple degrees of substitution being allowed unless otherwise stated.

Certain of the compounds described herein may contain one or more chiral atoms, or may otherwise be capable of existing as two enantiomers. The compounds of this invention include mixtures of enantiomers as well as purified enantiomers or enantiomerically enriched mixtures. Also included within the scope of the invention are the individual isomers of the compounds of this invention as well as any wholly or partially equilibrated mixtures thereof. The present invention also covers the individual isomers of the compounds represented by the formulas above as mixtures with isomers thereof in which one or more chiral centers are inverted. Also, it is understood that any tautomers and mixtures of tautomers of the compounds of this invention are considered to be within the scope of this invention.

Typically, the salts of the present invention are pharmaceutically acceptable salts. Salts encompassed within the term "pharmaceutically acceptable salts" refer to non-toxic salts of the compounds of this invention. Salts of the compounds of the present invention may comprise acid addition salts derived from a nitrogen on a substituent in a compound of this invention. Representative salts include the following salts: acetate, benzenesulfonate, benzoate, bicarbonate, bisulfate, bitartrate, borate, bromide, calcium edetate, camsylate, carbonate, chloride, clavulanate, citrate, dihydrochloride, edetate, edisylate, estolate, esylate, fumarate, gluceptate, gluconate, glutamate, glycollylarsanilate, hexylresorcinate, hydrabamine, hydrobromide, hydrochloride, hydroxynaphthoate, iodide, isethionate, lactate, lactobionate, laurate, malate, maleate, mandelate, mesylate, methylbromide, methylnitrate, methylsulfate, monopotassium maleate, mucate, napsylate, nitrate, N-methylglucamine, oxalate, pamoate (embonate), palmitate, pantothenate, phosphate/diphosphate, polygalacturonate, potassium, salicylate, sodium, stearate, subacetate, succinate, tannate, tartrate, teoclate, tosylate, triethiodide, trimethylammonium and valerate. Other salts, which are not pharmaceutically acceptable, may be useful in the preparation of compounds of this invention and these form a further aspect of the invention.

For purposes of this invention, it will be understood that phrases such as "a compound of formula (I), (II), or (III), and pharmaceutically acceptable salts, solvates and functional derivatives thereof" are intended to encompass the compound of formula (I),

(II), or (III), a functional derivative of a compound of formula (I), (II), or (III), a solvate of formula (I), (II), or (III) or any pharmaceutically acceptable combination of these. Thus, by way of non-limiting example used here for illustrative purposes the phrase "a compound of formula (I), (II), or (III), and pharmaceutically acceptable salts and solvates thereof" may include a pharmaceutically acceptable salt of formula (I), (II), or (III), a pharmaceutically acceptable solvate of a compound of formula (I), (II), or (III), or a pharmaceutically acceptable solvate of a salt of a compound of formula (I), (II), or (III).

While it is possible that, for use in therapy, therapeutically effective amounts of a compound of this invention, as well as salts, solvates and physiological functional derivatives thereof may be administered as the raw chemical, it is possible to present the active ingredient as a pharmaceutical composition. Accordingly, the invention further provides pharmaceutical compositions, which include therapeutically effective amounts of compounds of this invention and salts, solvates and physiological functional derivatives thereof, and one or more pharmaceutically acceptable carriers, diluents, or excipients. The compounds of this invention and salts, solvates and physiological functional derivatives thereof, are as described above. The carrier(s), diluent(s) or excipient(s) must be acceptable in the sense of being compatible with the other ingredients of the formulation and not deleterious to the recipient thereof. In accordance with another aspect of the invention there is also provided a process for the preparation of a pharmaceutical formulation including admixing a compound of this invention or salts, solvates and physiological functional derivatives thereof, with one or more pharmaceutically acceptable carriers, diluents or excipients.

Pharmaceutical formulations may be presented in unit dose forms containing a predetermined amount of active ingredient per unit dose. Such a unit may contain, for example, 0.5mg to 1 g, or 1 mg to 700mg, or 5mg to 10Omg of a compound of the invention, depending on the condition being treated, the route of administration and the age, weight and condition of the patient, or pharmaceutical formulations may be presented in unit dose forms containing a predetermined amount of active ingredient per unit dose. Preferred unit dosage formulations are those containing a daily dose or sub-dose, as herein above recited, or an appropriate fraction thereof, of an active ingredient.

Furthermore, such pharmaceutical formulations may be prepared by any of the methods well known in the pharmacy art.

Pharmaceutical formulations may be adapted for administration by any appropriate route, for example by the oral (including buccal or sublingual), rectal, nasal, topical (including buccal, sublingual or transdermal), vaginal or parenteral (including subcutaneous, intramuscular, intravenous or intradermal) route. Such formulations may

be prepared by any method known in the art of pharmacy, for example by bringing into association the active ingredient with the carrier(s) or excipient(s).

A therapeutically effective amount of a compound of the present invention will depend upon a number of factors including, for example, the age and weight of the animal, the precise condition requiring treatment and its severity, the nature of the formulation, and the route of administration, and will ultimately be at the discretion of the attendant physician or veterinarian. However, an effective amount of a compound of this invention for the treatment of cardiovascular disease, will generally be in the range of 0.1 to 100 mg/kg body weight of recipient (mammal) per day and more usually in the range of 1 to 10 mg/kg body weight per day. Thus, for a 70kg adult mammal, the actual amount per day would usually be from 70 to 700 mg and this amount may be given in a single dose per day or more usually in a number (such as two, three, four, five or six) of sub- doses per day such that the total daily dose is the same. An effective amount of a salt or solvate, or physiologically functional derivative thereof, may be determined as a proportion of the effective amount of the compound of the compound per se. It is envisaged that similar dosages would be appropriate for treatment of the other conditions referred to above.

The compounds of this invention, and salts, solvates and physiological functional derivatives thereof, are believed to have utility in chronic renal disease, congestive heart failure, and cardiovascular remodeling as a result of inhibition of the protein kinase SGK-1.

The present invention thus also provides compounds and pharmaceutically acceptable salts or solvates thereof, or physiologically functional derivatives thereof, for use in medical therapy, and particularly in the treatment of disorders mediated at least in part by SGK-1 activity. The SGK-1 activity referred to herein is any SGK-1 activity that is deemed to be desirable to modulate in a mammalian subject. SGK-1 activity may take the form of, for instance, an abnormal increase in activity, or an aberration in the timing and or control of SGK-1 activity. Such inappropriate activity may result then, for example, from overexpression or mutation of the protein kinase leading to inappropriate or uncontrolled activation. Alternatively, SGK-1 activity maybe deemed within a normal range but still maybe a good candidate for regulation, inhibition or modulation where it is determined that such activities would contribute to a desired result.

The present invention is directed to methods of regulating, modulating, or inhibiting SGK-1 for the prevention and/or treatment of disorders related to unregulated SGK-1 activity. In particular, the compounds of the present invention can also be used in the

treatment of certain forms of renal and cardiovascular disease as well as congestive heart failure.

A further aspect of the invention provides a method of treatment of a mammal suffering from a disorder mediated by SGK-1 activity, which includes administering to said subject an effective amount of a compound of the invention or a pharmaceutically acceptable salt, solvate, or a physiologically functional derivative thereof.

A further aspect of the present invention provides the use of a compound of this invention, or a pharmaceutically acceptable salt or solvate thereof, or a physiologically functional derivative thereof, in the preparation of a medicament for the treatment of a disorder characterized by SGK-1 activity.

The compounds of this invention may be made by a variety of methods, including standard chemistry. Any previously defined variable will continue to have the previously defined meaning unless otherwise indicated. Illustrative general synthetic methods are set out below and then specific compounds of the invention are prepared in the Working Examples.

Compounds of general formula (I), (II), or (III) may be prepared by methods known in the art of organic synthesis as set forth in part by the following synthesis schemes. In all of the schemes described below, it is well understood that protecting groups for sensitive or reactive groups are employed where necessary in accordance with general principles of chemistry. Protecting groups are manipulated according to standard methods of organic synthesis (T. W. Green and P. G. M. Wuts (1991) Protecting Groups in Organic Synthesis, John Wiley & Sons), herein incorporated by reference. These groups are removed at a convenient stage of the compound synthesis using methods that are readily apparent to those skilled in the art. The selection of processes as well as the reaction conditions and order of their execution shall be consistent with the preparation of compounds of Formula (I), (II), or (III). Those skilled in the art will recognize if a stereocenter exists in compounds of Formula (I), (II), or (III). Accordingly, the present invention includes both possible stereoisomers and includes not only racemic compounds but the individual enantiomers as well. When a compound is desired as a single enantiomer, it may be obtained by stereospecific synthesis or by resolution of the final product or any convenient intermediate. Resolution of the final product, an intermediate, or a starting material may be effected by any suitable method known in the art. See, for example, Stereochemistry of Organic Compounds by E. L Eliel, S. H. Wilen, and L. N. Mander (Wiley-lnterscience, 1994), herein incorporated by reference. The compounds of the present invention were prepared by the methods illustrated

in Schemes I through Vl.

Scheme

Reagents and Conditions: (a) PhB(OH)2, PdCl2(dppf), K2CO3, 2.5:1 dioxane/water, 80 0 C; (b) Br 2 , CHCI 3 or NBS, CHCI 3 ; (c) TsCI, Bu 4 NHSO 4 , 6N NaOH/CH 2 CI 2 , r.t, 1h or (i) LDA, THF, -78 0 C, (ii) TsCI, -78 0 C → r.t.; (d) 3-F-4-MeOPhB(OH) 2 , PdCI 2 (PPh 3 ) 2 , 2M Na 2 CO 3 , DMF, 9O 0 C or 3-F-4-MeOPhB(OH) 2 , PdCI 2 (dppf), K 2 CO 3 , 2.5:1 dioxane/water, 80 0 C, 12h, or 3-F-4-MeOPhB(OH) 2 , PdCI 2 (dppf), K 2 CO 3 , 2.5:1 dioxane/water, μv, 150 0 C, 5 min; (e) 2.5 N NaOH, dioxane, reflux, 1 h or Bu 4 NF, THF, 6O 0 C, 30m.

Azaindole (1-1) (the term azaindole may be used interchangeably in this specification with pyrrolo[2,3-b]pyridine(e)) is reacted with phenylboronic acid or any other suitable boronic acid or boronate under Suzuki coupling conditions to afford 5-aryl or 5- heteroaryl-7-azaindole (1-2). For example, 5-bromo-7-azaindole is coupled with phenylboronic acid using the combination of [1 ,1'- bis(diphenylphosphino)ferrocene]dichloropalladium(ll) and potassium carbonate in a mixture of 2.5:1 dioxane/water at a temperature of about 80 0 C to about reflux for about 1 h to 16h. The Suzuki reaction is well-known to those of skill in the art (for a review, see Suzuki, A. in Modern Arene Chemistry, Astruc, D. Ed.; Wiley-VCH Verlag: Weinheim,

Germany, 2002, pp. 53-106, herein incorporated by reference in its entirety). Intermediate (1-2) is brominated in the 3-position with bromine in chloroform or other suitable organic solvent at about 0 0 C to about room temperature for about 10 minutes to about 60 minutes, or NBS or a similar commercially available brominating reagent and a base such as triethylamine in an organic solvent such as dichloromethane or THF at about room temperature for about 1 hour to about 16 hours, and the product is treated with p- toluenesulfonyl chloride (tosyl chloride) or a similar commercially available tosyl reagent and a base such as aqueous sodium hydroxide in an organic solvent such as dichloromethane at a temperature of about 0 0 C to about room temperature for about 1 hour to about 12 hours to afford (1-3). Alternatively, the tosyl group may be introduced under anhydrous conditions by treatment of the intermediate with a base such as lithium diisopropylamide (LDA) in an organic solvent such as THF at a temperature of about -78 0 C to about -40 0 C for ten minutes to about 2 hours followed by addition of tosyl chloride at a temperature of about -78 0 C to about room temperature for about 30 minutes to about 3 hours. For example, 3-bromo-5-phenyl-7-azaindole hydrobromide was treated with tosyl chloride and tetra-Λ/-butylammonium hydrogen sulfate in a bilayer of dichloromethane and 2N sodium hydroxide to afford 3-bromo-1 -[(4-methylphenyl)sulfonyl]-5-phenyl-1 H- pyrrolo[2,3-jb]pyridine. The use of protecting groups. to mask reactive functionality is well- known to those of skill in the art, and other protecting groups are listed in standard reference volumes, such as Greene, "Protective Groups in Organic Synthesis" (published by Wiley-lnterscience), herein incorporated by reference in its entirety. Suzuki reaction of 1-3 with an appropriate aryl- or heteroarylboronic acid or boronate affords intermediate (I- 4). For example, 3-bromo-1-[(4-methylphenyl)sulfonyl]-5-phenyl-1 H-pyrrolo[2,3-fo]pyridine (\-3) is coupled with 3-fluoro-4-methoxyphenylboronic acid in the presence of bis(triphenylphosphine)dichloropalladium(ll) and sodium carbonate in DMF at a temperature of about 70 0 C to about 110 0 C for about 6 hours to about 24 hours to afford 3-[3-fluoro-4-(methyloxy)phenyl]-1 -[(4-methylphenyl)sulfonyl]-5-phenyl-1 H-pyrrolo[2,3- (b]pyridine (I-4). Removal of the tosyl protecting group is accomplished by treatment of the intermediate (I-4) with either aqueous base and a cosolvent such as dioxane at reflux or tetra-N-butylammonium fluoride in a suitable organic solvent such as THF at 60-90 0 C for a time of about 30 minutes to about 12 hours. For example, 3-[3-f luoro-4- (methyloxy)phenyl]-1 -[(4-methylphenyl)sulfonyl]-5-phenyl-1 /-/-pyrrolo[2,3-b]pyridine (1-4) is treated with tetra-N-butylammonium fluoride in THF at 60 0 C for 30 minutes to afford 3-[3- fluoro-4-(methyloxy)phenyl]-5-phenyl-1 H-pyrrolo[2,3-b]pyridine (I-5);

Reagents and Conditions: (a) TFAA, CH2CI2, O 0 C, 30 min.; (b) Br2, CH2CI2, r.t., 30 min.; (c) TsCI, NaOH, CH2CI2, r.t. 1h.; (d) 4-aminomethylphenylboronic acid, PdCl2(dppf), K2CO3, 2.5:1 dioxane/water, 8O 0 C; (e) 2.5 N NaOH, dioxane, reflux, 1 h.

Certain protecting groups beyond the N-1 protecting group of the 7-azaindole core may be required to complete the synthesis of the compounds of interest. Those groups requiring protection would be recognizable to those skilled in the art and the choice of protecting group would be made based on the nature of the functionality to be protected. For example, Scheme Il shows that the protection of the intermediate (11-1) can be accomplished using trifluoroacetic anhydride or any other commercially available trifluoroacetylating agent in an organic solvent such as dichloromethane at a temperature of about -10 0 C to about 10 0 C for about 10 minutes to about 6h. The remainder of the synthetic scheme then follows the same general route as outlined in Scheme I. It should be noted that there may or may not be additional steps required to remove the protecting group prior to isolation of the compound of interest. Those steps would be recognizable to those skilled in the art.

Further manipulations of the functional groups on the aryl rings at either the 3- or the 5-position of the azaindole core may be necessary to complete the synthesis of the compounds of interest. These modifications can take place either before or after the removal of the tosyl protecting group at the 1 -position. For example, compound of interest (III-1) could be further manipulated to compound of interest (III-2). In another example, intermediate (IV-I) undergoes functional group manipulation and subsequent protecting group removal to provide compound of interest (IV-2). Such functional group transformations, conditions to effect such functional group transformations, and stages at which the transformations are best carried out are known to those skilled in the art.

Vl-I Vl-Il

Reagents and Conditions: (a) i. n-BuLi, (/-PrO)B, THF; ii. H + . Certain boronate esters or boronic acids may require preparation as intermediates.

Conversion to the pinacol boronate ester can be accomplished by palladium-catalyzed coupling of the intermediate aryl bromide or iodide with bis(pinacolato)diboron, as exemplified by the conversion of intermediate (V-I) to (V-Il) (see J. Org. Chem. 1995, 60, 7508; J. Org. Chem. 2003, 68, 3729.). Alternatively, direct conversion to the boronic acid can be carried out by trapping an arylmetal intermediate, generated by treating an aryl bromide or iodide with a reagent such as n-butyllithium, with a trialkylborate such as trimethylborate or triisopropylborate followed by acidic workup as exemplified by the conversion of intermediate (Vl-I) to boronic acid (Vl-Il) in Scheme Vl (see J. Med. Chem. 2000, 43, 517.). Such functional group transformations, conditions to effect such functional group transformations, and stages at which the transformations are best carried out are known to those skilled in the art.

Reagents and Conditions: (a) LDA, MeI, THF

Certain boronate esters or boronic acid intermediates may require modification. For example, treatment of boronate ester (VII-I) with lithium diisopropylamide (LDA) followed by addition of iodomethane provides the intermediate (VII-I). Such functional group transformations, conditions to effect such functional group transformations, and stages at which the transformations are best carried out are known to those skilled in the art.

[1 ,1 '-bis(diphenylphosphino)ferrocene]dichloropalladium(ll) complex with dichloromethane (246 mg, 0.30 mmol, 0,05 equiv) was added to a suspension of 3-bromo- 1-[(4-methylphenyl)sulfonyl]-5-phenyl-1 H-pyrrolo[2,3-b]pyridine (2.57g, 6.01 mmol, 1 equiv), 4-carboxyphenylboronic acid (1.2 g, 7.21 mmol, 1.2 equiv) and potassium carbonate (2.49 g, 18.0 mmol, 3 equiv) in 2.5:1 dioxane/water (60 ml_). The reaction flask was equipped with a water-cooled condenser, and the reaction mixture was heated to reflux under a nitrogen atmosphere. After three hours, the reaction mixture was cooled to room temperature and acidified with concentrated HCI (ca. 8 ml_). The mixture was then filtered through a pad of Celite, and the filtrate was partitioned between ethyl acetate (100 ml_) and water (100 mL). The layers were separated, and the aqueous layer was further extracted with ethyl acetate (2 50-mL portions). The combined organics were dried over sodium sulfate and were concentrated. The 4-[5-phenyl-1 -(toluene-4-sulfonyl)-1 H- pyrrolo[2,3-b]pyridin-3-yl)-benzoic acid was used directly in the next step without further purification. e) 4-(5-phenyl-1 H-pyrrolor2,3-blpyridin-3-yl)-benzoic acid

The crude 4-[5-phenyl-1 -(toluene-4-sulfonyl)-1 H-pyrrolo[2,3-b]pyridin-3-yl)-benzoic acid was taken up in a mixture of methanol (50 mL) and 2.5 N NaOH (20 mL). The reaction mixture was heated at 50 C for 30 minutes and cooled to room temperature. The reaction mixture was acidified with concentrated HCI and then partitioned between ethyl acetate (100 mL) and water (100 mL). The precipitate that formed was collected by filtration and set aside. The aqueous layer was further extracted with ethyl acetate

(2 50-mL portions), and the combined organics were dried over anhydrous sodium sulfate and concentrated. The original precipitate was combined with the residue from the organics, and the combination was stirred with 10% methanol in dichloromethane (60 mL)

for 30 min. The insolubles were collected by filtration, and the filtrate was concentrated in vacuo and stirred again with 10% methanol in dichloromethane (30 ml_). The insolubles were again collected by filtration and combined with the first crop. This process was repeated once more to provide 4-(5-phenyl-1 H-pyrrolo[2,3-b]pyridin-3-yl)-benzoic acid (1.13g, 60%). 1 H NMR (400 MHz, CD 3 OD) δ 8.54 (s, 2H), 8.14 (d, J = 8 Hz, 2H), 7.87 (m, 3H), 7.73 (d, J = 8.8 Hz, 2H), 7.51 (t, J = 7.6 Hz, 2H), 7.40 (t, J = 7.2 Hz. 1 H).
