The invention had the object of finding novel compounds having valuable properties, in particular those which can be used for the preparation of medicaments.

It has been found that the compounds of the formula I and their salts have very valuable pharmacological properties and are well tolerated. In particu- lar, they exhibit factor Xa-inhibiting properties and can therefore be employed for combating and preventing thromboembolic disorders, such as thrombosis, myocardial infarction, arteriosclerosis, inflammation, apo- plexia, angina pectoris, restenosis after angioplasty and claudicatio intermittens.

The compounds of the formula I according to the invention may further- more be inhibitors of the coagulation factors factor Vlla, factor IXa and thrombin in the blood coagulation cascade.

Aromatic amidine derivatives having an antithrombotic action are dis- closed, for example, in EP 0 540 051 B1, WO 00/71508, WO 00/71511, WO 00/71493, WO 00/71507, WO 00/71509, WO 00/71512, WO 00/71515 and WO 00/71516. Cyclic guanidines for the treatment of thromboembolic disorders are described, for example, in WO 97/08165.

Aromatic heterocyclic compounds having factor Xa-inhibitory activity are disclosed, for example, in WO 96/10022. Substituted N- [ (aminoimino- methyl) phenylalkyl] azaheterocyclylamides as factor Xa inhibitors are described in WO 96/40679.

The antithrombotic and anticoagulant effect of the compounds according to the invention is attributed to the inhibitory action against activated coagulation protease, known by the name factor Xa, or to the inhibition of other activated serine proteases, such as factor Vlla, factor IXa or thrombin.

Factor Xa is one of the proteases involved in the complex process of blood coagulation. Factor Xa catalyses the conversion of prothrombin into thrombin. Thrombin cleaves fibrinogen into fibrin monomers, which, after crosslinking, make an elementary contribution to thrombus formation.

Activation of thrombin may result in the occurrence of thromboembolic disorders. However, inhibition of thrombin may inhibit the fibrin formation involved in thrombus formation.

The inhibition of thrombin can be measured, for example, by the method of G. F. Cousins et al. in Circulation 1996,94,1705-1712.

Inhibition of factor Xa can thus prevent the formation of thrombin.

The compounds of the formula I according to the invention and their salts engage in the blood coagulation process by inhibiting factor Xa and thus inhibit the formation of thrombuses.

The inhibition of factor Xa by the compounds according to the invention and the measurement of the anticoagulant and antithrombotic activity can be determined by conventional in-vitro or in-vivo methods. A suitable method is described, for example, by J. Hauptmann et al. in Thrombosis and Haemostasis 1990, 63,220-223.

The inhibition of factor Xa can be measured, for example, by the method of T. Hara et al. in Thromb. Haemostas. 1994,71,314-319.

Coagulation factor Vlla initiates the extrinsic part of the coagulation cascade after binding to tissue factor and contributes to the activation of factor X to give factor Xa. Inhibition of factor Vlla thus prevents the formation of factor Xa and thus subsequent thrombin formation.

The inhibition of factor Vlla by the compounds according to the invention and the measurement of the anticoagulant and antithrombotic activity can be determined by conventional in-vitro or in-vivo methods. A conventional method for the measurement of the inhibition of factor Vlla is described, for example, by H. F. Ronning et al. in Thrombosis Research 1996,84, 73-81.

Coagulation factor IXa is generated in the intrinsic coagulation cascade and is likewise involved in the activation of factor X to give factor Xa.

Inhibition of factor IXa can therefore prevent the formation of factor Xa in a different way.

The inhibition of factor IXa by the compounds according to the invention and the measurement of the anticoagulant and antithrombotic activity can be determined by conventional in-vitro or in-vivo methods. A suitable method is described, for example, by J. Chang et al. in Journal of Biological Chemistry 1998, 273,12089-12094.

The compounds according to the invention may furthermore be used for the treatment of tumours, tumour illnesses and/or tumour metastases.

A correlation between tissue factor TF/factor Vlla and the development of various types of cancer has been indicated by T. Taniguchi and N. R.

Lemoine in Biomed. Health Res. (2000), 41 (Molecular Pathogenesis of Pancreatic Cancer), 57-59.

The compounds according to the invention are furthermore used for illnesses in which blood coagula- tion makes a crucial contribution to the course of the illness or represents a source of secondary pathology, such as, for example, in cancer, includ- ing metastasis, inflammatory disorders, including arthritis, and diabetes.

In the treatment of the illnesses described, the compounds according to the invention are also employed in combination with other thrombolytically active compounds, such as, for example, with"tissue plasminogen activator"t-PA, modified t-PA, streptokinase or urokinase. The compounds according to the invention are given either at the same time as or before or after the other substances mentioned.

Preference is furthermore given to the following compounds of the formula I, which, as direct prodrug compounds, can be converted into the corre- sponding amidino or aminocarbonyl derivatives and in which R1 is CN or N- [3- (5-methyl-1, 2,4-oxadiazol-3-yl) phenyl]-2- (2'-methanesulfonyl- biphenyl-4-oxyl)-2-phenylacetamide, N- [3- (5-methyl-1,2,4-oxadiazol-3-yl) phenyl]-2- (3-acetylamino- phenoxy) acetamide, N- [3- (5-methyl-1,2,4-oxadiazol-3-yl) phenyl]-2- (2'-methanesulfonyl- biphenyl-4-oxyl) acetamide, N- [3- (5-methyl-1, 2,4-oxadiazol-3-yl) phenyl]-2- (3-ureidophenoxy)- acetamide, N-[3-(5-methyl-1, 2,4-oxadiazol-3-yl) phenyl]-2- (3-ureidophenoxy)-2- phenylacetamide, N- [3- (5-methyl-1, 2,4-oxadiazol-3-yl) phenyl]-2- [4- (2-oxopiperidin-1- yl) phenylamino] acetamide, N-[3-(5-methyl-1, 2,4-oxadiazol-3-yl) phenyl]-2- [4- (2-oxopiperidin-1- yl) phenylamino]-2-phenylacetamide,

The compounds of the formula I and also the starting materials for their preparation are, in addition, prepared by methods known per se, as described in the literature (for example in the standard works, such as Houben-Weyl, Methoden der organischen Chemie [Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart), to be precise under reaction conditions which are known and suitable for the said reactions. Use can also be made here of variants which are known per se, but are not mentioned here in greater detail.

If desired, the starting materials can also be formed in situ so that they are not isolated from the reaction mixture, but instead are immediately con- verted further into the compounds of the formula 1.

Compounds of the formula I can preferably be obtained by liberating com- pounds of the formula I from one of their functional derivatives by treat- ment with a solvolysing or hydrogenolysing agent.

Preferred starting materials for the sofvolysis or hydrogenolysis are those which conform to the formula 1, but contain corresponding protected amino and/or hydroxyl groups instead of one or more free amino and/or hydroxyl groups, preferably those which carry an amino-protecting group instead of an H atom bonded to an N atom, in particular those which carry an R'-N group, in which R'is an amino-protecting group, instead of an HN group, and/or those which carry a hydroxyl-protecting group instead of the H atom of a hydroxyl group, for example those which conform to the formula 1, but carry a-COOR"group, in which R"is a hydroxyl-protecting group, instead of a-COOH group.

Preferred starting materials are also the oxadiazole derivatives, which can be converted into the corresponding amidino compounds.

The amidino group can be liberated from its oxadiazole derivative by, for example, treatment with hydrogen in the presence of a catalyst (for example Raney nickel). Suitable solvents are those indicated below, in particular alcohols, such as methanol or ethanol, organic acids, such as acetic acid or propionic acid, or mixtures thereof. The hydrogenolysis generally carried out at temperatures between about 0 and 100° and pressures between about 1 and 200 bar, preferably at 20-30° (room temperature) and 1-10 bar.

The oxadiazole group is introduced, for example, by reaction of the cyano compounds with hydroxylamine and reaction with phosgene, dialkyl carbonate, chloroformic acid esters, N, N'-carbonyldiimidazole or acetic anhydride.

It is also possible for a plurality of-identical or different-protected amino and/or hydroxyl groups to be present in the molecule of the starting material. If the protecting groups present are different from one another, they can in many cases be cleaved off selectively.

The term"amino-protecting group"is known in general terms and relates to groups which are suitable for protecting (blocking) an amino group against chemical reactions, but which are easy to remove after the desired chemical reaction has been carried out elsewhere in the molecule. Typical of such groups are, in particular, unsubstituted or substituted acyl, aryl, aralkoxymethyl or aralkyl groups. Since the amino-protecting groups are removed after the desired reaction (or reaction sequence), their type and size are furthermore not crucial ; however, preference is given to those having 1-20, in particular 1-8, carbon atoms. The term"acyl group"is to be understood in the broadest sense in connection with the present process.

It includes acyl groups derived from aliphatic, araliphatic, aromatic or heterocyclic carboxylic acids or sulfonic acids, and, in particular, alkoxy- carbonyl, aryloxycarbonyl and especially aralkoxycarbonyl groups.

Examples of such acyl groups are alkanol, such as acetyl, propionyl and butyryl ; aralkanoyl, such as phenylacetyl ; aroyl, such as benzoyl and tolyl ; aryloxyalkanoyl, such as POA; alkoxycarbonyl, such as methoxycarbonyl, ethoxycarbonyl, 2,2,2-trichloroethoxycarbonyl, BOC (tert-butoxycarbonyl) and 2-iodoethoxycarbonyl ; aralkoxycarbonyl, such as CBZ ("carbo- benzoxy"), 4-methoxybenzyloxycarbonyl and FMOC; and arylsulfonyl, such as Mtr. Preferred amino-protecting groups are BOC and Mtr, furthermore CBZ, Fmoc, benzyl and acetyl.

The term"hydroxyl-protecting group"is likewise known in general terms and relates to groups which are suitable for protecting a hydroxyl group against chemical reactions, but are easily removable after the desired chemical reaction has been carried out elsewhere in the molecule. Typical of such groups are the above-mentioned unsubstituted or substituted aryl,

aralkyl or acyl groups, furthermore also alkyl groups. The nature and size of the hydroxyl-protecting groups are not crucial since they are removed again after the desired chemical reaction or reaction sequence; preference is given to groups having 1-20, in particular 1-10, carbon atoms. Examples of hydroxyl-protecting groups are, inter alia, benzyl, 4-methoxybenzyl, p-nitrobenzoyl, p-toluenesulfonyl, ter-butyl and acetyl, where benzyl and ter-butyl are particularly preferred.

The compounds of the formula I are liberated from their functional deriva- tives-depending on the protecting group used-for example using strong acids, advantageously using TFA or perchloric acid, but also using other strong inorganic acids, such as hydrochloric acid or sulfuric acid, strong organic carboxylic acids, such as trichloroacetic acid, or sulfonic acids, such as benzene-or p-toluenesulfonic acid. The presence of an additional inert solvent is possible, but is not always necessary. Suitable inert sol- vents are preferably organic, for example carboxylic acids, such as acetic acid, ethers, such as tetrahydrofuran or dioxane, amides, such as DMF, halogenated hydrocarbons, such as dichloromethane, furthermore also alcohols, such as methanol, ethanol or isopropanol, and water. Mixtures of the above-mentioned solvents are furthermore suitable. TFA is preferably used in excess without addition of a further solvent, and perchloric acid is preferably used in the form of a mixture of acetic acid and 70% perchloric acid in the ratio 9: 1. The reaction temperatures for the cleavage are advantageously between about 0 and about 50°, preferably between 15 and 30° (room temperature).

The BOC, O-but and Mtr groups can, for example, preferably be cleaved off using TFA in dichloromethane or using approximately 3 to 5N HCI in dioxane at 15-30°, and the FMOC group can be cleaved off using an approximately 5 to 50% solution of dimethylamine, diethylamine or piperi- dine in DMF at 15-30°

Protecting groups which can be removed hydrogenolytically (for example CBZ, benzyl or the liberation of the amidino group from its oxadiazole derivative) can be cleaved off, for example, by treatment with hydrogen in the presence of a catalyst (for example a noble-metal catalyst, such as palladium, advantageously on a support, such as carbon). Suitable sol- vents here are those indicated above, in particular, for example, alcohols, such as methanol or ethanol, or amides, such as DMF. The hydrogenolysis generally carried out at temperatures between about 0 and 100° and pressures between about 1 and 200 bar, preferably at 20-30° and 1-10 bar. Hydrogenolysis of the CBZ group succeeds well, for example, on 5 to 10% Pd/C in methanol or using ammonium formate (instead of hydrogen) on Pd/C in methanol/DMF at 20-30°.

Examples of suitable inert solvents are hydrocarbons, such as hexane, petroleum ether, benzene, toluene or xylene ; chlorinated hydrocarbons, such as trichloroethylene, 1,2-dichloroethane, tetrachloromethane, trifluoromethylbenzene, chloroform or dichloromethane ; alcohols, such as methanol, ethanol, isopropanol, n-propanol, n-butanol or tert-butanol ; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran (THF) or dioxane ; glycol ethers, such as ethylene glycol monomethyl or monoethyl ether or ethylene glycol dimethyl ether (diglyme) ; ketones, such as acetone or butanone; amides, such as acetamide, dimethylacetamide, N-methyl- pyrrolidone (NMP) or dimethylformamide (DMF); nitriles, such as acetonitrile ; sulfoxides, such as dimethyl sulfoxide (DMSO); carbon disulfide ; carboxylic acids, such as formic acid or acetic acid; nitro com- pounds, such as nitromethane or nitrobenzene; esters, such as ethyl acetate, or mixtures of the said solvents.

A cyano group is converted into an amidino group by reaction with, for example, hydroxylamine followed by reduction of the N-hydroxyamidine using hydrogen in the presence of a catalyst, such as, for example, Pd/C.

In order to prepare an amidine of the formula 1, it is also possible to adduct ammonia onto a nitrile. The adduction is preferably carried out in a number of steps by, in a manner known per se, a) converting the nitrile into a thio- amide using H2S, converting the thioamide into the corresponding S-alkyl- imidothioester using an alkylating agent, for example CH31, and reacting the thioester in turn with NH3 to give the amidine, b) converting the nitrile into the corresponding imidoester using an alcohol, for example ethanol in the presence of HCI, and treating the imidoester with ammonia (Pinner synthesis), or c) reacting the nitrile with lithium bis (trimethylsilyl) amide, and subsequently hydrolysing the product.

Esters can be saponified, for example, using acetic acid or using NaOH or KOH in water, water/THF or water/dioxane, at temperatures between 0 and 100°.

Free amino groups can furthermore be acylated in a conventional manner using an acid chloride or anhydride or alkylated using an unsubstituted or substituted alkyl halide, or reacted with CH3-C (=NH)-Oet, advantageously in an inert solvent, such as dichloromethane or THF and/or in the presence of a base, such as triethylamine or pyridine, at temperatures between-60 and +30°.

If desired, the starting materials can also be formed in situ so that they are not isolated from the reaction mixture, but instead are immediately con- verted further into the compounds of the formula 1.

Compounds of the formula I in which R', R2 and T are in protected form can preferably be obtained by reacting compounds of the formula 11 with compounds of the formula III.

The reaction is generally carried out in an inert solvent, in the presence of an acid-binding agent, preferably an alkali or alkaline earth metal hydro- xide, carbonate or bicarbonate, or in the presence of another salt of a

weak acid of the alkali or alkaline earth metals, preferably of potassium, sodium, calcium or caesium. The addition of an organic base, such as triethylamine, dimethylaniline, pyridine or quinoline, may also be favour- able. Depending on the conditions used, the reaction time is between a few minutes and 14 days, and the reaction temperature is between about 0° and 150°, normally between 20° and 130°.

Examples of suitable inert solvents are water; hydrocarbons, such as hexane, petroleum ether, benzene, toluene or xylene ; chlorinated hydro- carbons, such as trichloroethylene, 1,2-dichloroethane, carbon tetra- chloride, chloroform or dichloromethane ; alcohols, such as methanol, ethanol, isopropanol, n-propanol, n-butanol or tert-butanol ; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran (THF) or dioxane; glycol ethers, such as ethylene glycol monomethyl or monoethyl ether or ethylene glycol dimethyl ether (diglyme) ; ketones, such as acetone or butanone; amides, such as acetamide, dimethylacetamide or dimethyl- formamide (DMF); nitriles, such as acetonitrile ; sulfoxides, such as dimethyl sulfoxide (DMSO); carbon disulfide ; carboxylic acids, such as formic acid or acetic acid; nitro compounds, such as nitromethane or nitrobenzene; esters ; such as ethyl acetate, or mixtures of the said solvents.

The starting compounds of the formulae 11 and III are generally known. If they are novel, however, they can be prepared by methods known per se.

In the compounds of the formula 111, L is preferably Cl, Br, I or a reactively modified OH group, such as, for example, an activated ester, an imida- zolide or alkylsulfonyloxy having 1-6 carbon atoms (preferably methyl- sulfonyloxy or trifluoromethylsulfonyloxy) or arylsulfonyloxy having 6-10 carbon atoms (preferably phenyl-or p-tolylsulfonyloxy).

A base of the formula I can be converted into the associated acid-addition salt using an acid, for example by reaction of equivalent amounts of the base and the acid in an inert solvent, such as ethanol, followed by evapo- ration. Suitable acids for this reaction are, in particular, those which give physiologically acceptable salts. Thus, it is possible to use inorganic acids, for example sulfuric acid, nitric acid, hydrohalic acids, such as hydrochloric acid or hydrobromic acid, phosphoric acids, such as orthophosphoric acid, or sulfamic acid, furthermore organic acids, in particular aliphatic, alicyclic, araliphatic, aromatic or heterocyclic monobasic or polybasic carboxylic, sulfonic or sulfuric acids, for example formic acid, acetic acid, propionic acid, pivalic acid, diethylacetic acid, malonic acid, succinic acid, pimelic acid, fumaric acid, maleic acid, lactic acid, tartaric acid, malic acid, citric acid, gluconic acid, ascorbic acid, nicotinic acid, isonicotinic acid, methane- or ethanesulfonic acid, ethanedisulfonic acid, 2-hydroxyethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, naphthalenemono-and -disulfonic acids, and laurylsulfuric acid. Salts with physiologically unacceptable acids, for example picrates, can be used for the isolation and/or purification of the compounds of the formula 1.

On the other hand, compounds of the formula I can be converted into the corresponding metal salts, in particular alkali metal or alkaline earth metal salts, or into the corresponding ammonium salts using bases (for example sodium hydroxide, potassium hydroxide, sodium carbonate or potassium carbonate).

It is also possible to use physiologically acceptable organic bases, such as, for example, ethanolamine.

Compounds of the formula I according to the invention may be chiral owing to their molecular structure and may accordingly occur in various enantio- meric forms. They can therefore exist in racemic or in optically active form.

Since the pharmaceutical activity of the racemates or stereoisomers of the compounds according to the invention may differ, it may be desirable to use the enantiomers. In these cases, the end product or even the interme- diates can be separated into enantiomeric compounds by chemical or physical measures known to the person skilled in the art or even employed as such in the synthesis.

In the case of racemic amines, diastereomers are formed from the mixture by reaction with an optically active resolving agent. Examples of suitable resolving agents are optically active acids, such as the R and S forms of tartaric acid, diacetyltartaric acid, dibenzoyltartaric acid, mandelic acid, malic acid, lactic acid, suitable N-protected amino acids (for example N- benzoylproline or N-benzenesulfonylproline), or the various optically active camphorsulfonic acids. Also advantageous is chromatographic enantiomer resolution with the aid of an optically active resolving agent (for example dinitrobenzoylphenylglycine, cellulose triacetate or other derivatives of carbohydrates or chirally derivatised methacrylate polymers immobilised on silica gel). Suitable eluents for this purpose are aqueous or alcoholic solvent mixtures, such as, for example, hexane/isopropanol/acetonitrile, for example in the ratio 82: 15: 3.

The invention furthermore relates to the use of the compounds of the formula I and/or their physiologically acceptable salts for the preparation of a medicament (pharmaceutical preparation), in particular by non-chemical methods. They can be converted here into a suitable dosage form together with at least one solid, liquid and/or semi-liquid excipient or assistant and, if desired, in combination with one or more further active ingredients.

The invention furthermore relates to medicaments comprising at least one compound of the formula I and/or its pharmaceutical usable derivatives, solvates and stereoisomers, including mixtures thereof in all ratios ; and, if desired, excipients and/or assistants.

These preparations can be used as medicaments in human or veterinary medicine. Suitable excipients are organic or inorganic substances which are suitable for enteral (for example oral), parenteral or topical administra- tion and do not react with the novel compounds, for example water, vege- table oils, benzyl alcohols, alkylene glycols, polyethylene glycols, glycerol triacetate, gelatine, carbohydrates, such as lactose or starch, magnesium stearate, talc or Vaseline. Suitable for oral administration are, in particular, tablets, pills, coated tablets, capsules, powders, granules, syrups, juices or drops, suitable for rectal administration are suppositories, suitable for parenteral administration are solutions, preferably oil-based or aqueous solutions, furthermore suspensions, emulsions or implants, and suitable for topical application are ointments, creams or powders or also as nasal sprays. The novel compounds may also be lyophilised and the resultant lyophilisates used, for example, to prepare injection preparations. The preparations indicated may be sterilised and/or comprise assistants, such as lubricants, preservatives, stabilisers and/or wetting agents, emulsifying agents, salts for modifying the osmotic pressure, buffer substances, colorants and flavours and/or a plurality of further active ingredients, for example one or more vitamins.

The compounds of the formula I and their physiologically acceptable salts can be used for combating and preventing thromboembolic disorders, such as thrombosis, myocardial infarction, arteriosclerosis, inflammation, apoplexia, angina pectoris, restenosis after angioplasty, claudicatio intermittens, tumours, tumour diseases and/or tumour metastases.

In general, the substances according to the invention are preferably administered in doses between about 1 and 500 mg, in particular between 5 and 100 mg, per dosage unit. The daily dose is preferably between about 0.02 and 10 mg/kg of body weight. However, the specific dose for each patient depends on a wide variety of factors, for example on the

efficacy of the specific compound employed, on the age, body weight, gen- eral state of health, sex, on the diet, on the time and method of administra- tion, on the excretion rate, medicament combination and severity of the particular illness to which the therapy applies. Oral administration is pre- ferred.

The invention furthermore relates to medicaments comprising at least one compound of the formula I and/or its pharmaceutical usable derivatives, solvates and stereoisomers, including mixtures thereof in all ratios, and at least one further medicament active ingredient.

The invention also relates to a set (kit) consisting of separate packs of (a) an effective amount of a compound of the formula I and/or its pharmaceutical usable derivatives, solvates and stereoisomers, including mixtures thereof in all ratios, and (b) an effective amount of a further medicament active ingredient.

The set comprises suitable containers, such as boxes, individual bottles, bags or ampoules. The set may, for example, comprise separate ampoules each containing an effective amount of a compound of the formula I and/or its pharmaceutically usable derivatives, solvates and stereoisomers, including mixtures thereof in all ratios, and an effective amount of a further medicament active ingredient in dissolved or lyophilised form.

The invention furthermore relates to the use of compounds of the formula I and/or their pharmaceutical usable derivatives, solvates and stereo- isomers, including mixtures thereof in all ratios, for the preparation of a medicament for the treatment of thrombosis, myocardial infarction, arteriosclerosis, inflammation, apoplexia, angina

pectoris, restenosis after angioplasty, claudicatio intermittens, tumours, tumour diseases and/or tumour metastases, in combination with at least one further medicament active ingredient.
