Abstract

Novel 5-methylisoxazole-4-carboxamides of the formula I are prepared in which R denotes a mono-, di- or trinuclear, unsaturated heterocyclic radical having 3 to 13 carbon atoms and one, two, three or four hetero atoms from the group comprising oxygen, sulphur and nitrogen, where at most one of the hetero atoms is other than nitrogen, in the ring system, which radical is unsubstituted or ring-substituted one, two or three times by C1-C3-alkyl, C1-C3-alkoxy, halogen, nitro, hydroxyl, carboxyl, carbamoyl or oxo, and their physiologically tolerable acid addition salts, by reaction of corresponding carboxylic acid derivatives, namely the corresponding acid halides, esters or anhydrides, with amines of the formula H2N-R. The compounds of the formula I are distinguished in particular by anti-inflammatory, antipyretic and analgesic properties combined with low toxicity and good gastric tolerability.

Description

This invention relates to isoxazole derivatives and is an improvement in, or modification of, the invention of Patent Specification No. 43136.
Patent Specification No. 43136 describes and claims 5 5 - methyl - isoxazole - 4 - carboxylic acid anilides of the general formula 2 in which R and R , which may be identical or different, each represents a hydrogen atom; an alkyl group of 1, 2 or 3 carbon atoms, an alkoxy group of 1, 2 or 3 carbon atoms, an alkylthio group of 1, 2 or 3 carbon atoms, the alkyl groups of which may be substituted partly or totally by identical or different halogen atoms, for example, fluorine, chlorine, bromine or iodine atoms, or represents a halogen atom, for example, a fluorine, chlorine, bromine or iodine atom, or represents a nitro or cyano group or an alkoxycarbonyl group having 1, 2 or 3 carbon atoms in the alkyl moiety.
R represents an alkyl group of 1, 2 or 3 carbon atoms, an alkoxy group of 1, 2 or 3 carbon atoms, an alkylthio group of 1, 2 or 3 carbon atoms, the alkyl groups of which may be substituted partly or totally by identical or different halogen atoms, for example, fluorine, chlorine, bromine or iodine atoms, or represents a halogen atom, for example, a fluorine, chlorine, bromine or iodine atom, or represents a nitro or cyano group or an alkoxycarbonyl group having 1, or 3 carbon atoms in the alkyl moiety; or represents a phenyl group which may carry one or two substituents selected from fluorine, chlorine, bromine and iodine atoms, alkyl groups of 1, 2 or 3 carbon atoms and alkoxy groups of 1, 2 or 3 carbon atoms, or a phenoxy group which may carry one or two substituents selected from fluorine, chlorine, bromine and iodine atoms, alkyl groups of 1, 2 or 3 carbon atoms and alkoxy groups of 1, 2 or 3 carbon atoms; 2 3 or in which R stands for a hydrogen atom, and R and R together represent a methylenedioxy group or, together with the phenyl ring, to which they are linked, represent 3 a naphthalene ring; with the proviso that R does not repre1 2 sent a methyl group when R and R both represent hydrogen atoms.
We have now found that pharmacological properties are also shown by 5 - methylisoxazole - 4 - carboxylic acid amides of the general formula O c' (I) in which R represents a mononuclear, binuclear or trinuclear, unsaturated heterocyclic radical having in the ring system - 4 3 to 13 carbon atoms and one, two, three or four hetero atoms selected from oxygen, sulphur and nitrogen, one of which at most is other than nitrogen, which ring system is unsubstituted or substituted by one or more substituents, preferably by one, two or three substituents selected from alkyl and alkoxy radicals each having one, two or three carbon atoms, by halogen atoms, i.e. fluorine, chlorine, bromine and iodine atoms, nitro, hydroxy and carboxy groups, unsubstituted and substituted carbamoyl radicals and oxo groups. Preferably, if there is more than one substituent, the substituents are the same.
The present invention also provides a salt, especially a physiologically tolerable acid addition salt, of a compound of the general formula I.
The ring system may include a carbocyclic ring or rings, provided it contains at least one heterocyclic ring. The rings may be aromatic or non-aromatic and usually all are unsaturated.
Suitable radicals represented by R are, for example, thienyl, pyridyl, pyrimidinyl, pyrazinyl, pyridazinyl, irnidazolyl, thiazolyl, thiazolinyl, oxazolyl, thiadiazolyl, benzothiazolyl, benzoxazolyl, benzimidazolyl, quinolyl, pyrazolyl, acridinyl and tetrazolyl radicals, each of which may be unsubstituted or substituted as specified.
Preferred compounds are those of the general formula I in which R represents a pyridyl radical which is unsubstituted or substituted by one, two or three of the same or different halogen atoms, i.e. fluorine, chlorine, bromine and iodine atoms, or represents a pyrimidinyl radical which is unsubstituted or substituted once, twice or three times by a (C^—C^)-alkyl radical and/or by the oxo group, or a thiazolyl radical which is unsubstituted or substituted by a nitro group.
The present invention also provides a process for the 5 preparation of a compound of the general formula I or a salt thereof, which comprises reacting a 5 - methylisoxazole - 4carboxylic acid derivative of the general formula in which X represents a) a halogen atom, preferably a chlorine or bromine atom; b) a YO-group, in which Y represents (i) a phenyl radical which is unsubstituted or substituted by one, two or three substituents selected 15 from fluorine, chlorine, bromine and iodine atoms, and methyl, ethyl, methoxy, ethoxy or trifluoromethyl, nitro and cyano groups, or (ii) the acyl radical corresponding to the formula (II) that is (II1) ^46269 - 6 or c) a ZO—CO—O-group in which Z represents a (C^—c^)alkyl radical, a benzyl radical or a phenyl radical; or another reactive functional derivative of the carboxylic acid corresponding to the general formula II, with an unsaturated heterocyclic amine of the general formula H2N~r (III) in which R has the meaning given above, or with a salt thereof.
Preferably, a substituted phenyl radical Y contains one substituent or two or three of the same substituents.
The reaction is advantageously carried out in a dispersing agent or a solvent that is inert towards the reactants. Suitable polar solvents that may be used are, for example, nitriles, e.g. acetonitrile; ethers, e.g. diethyl ether, tetrahydrofuran or dioxan; and alcohols, e.g. methanol, ethanol, propanol or isopropanol. Non-polar solvents, e.g. benzene, toluene and cyclohexane, may also be used.
Preferably the compound of the general formula II is the carboxylic acid chloride. It is advantageous in this case for the reaction to be carried out in the presence of an acid-binding agent, e.g. potassium or sodium carbonate, an alkali metal hydroxide, alkaline earth metal hydroxide, alkali metal alcoholate or alkaline earth metal alcoholate, an organic base, for example triethylamine, pyridine, picoline or quinoline or the amine reactant used in excess, at temperatures of from 0 to 160°C', preferably from 20 to 80°C. The reaction time may be from a few minutes to two hours.
A 5- methylisoxazole - 4 - carboxylic acid derivative of the general formula II required as starting material may - 7 be obtained in accordance with the method described in German Patent No. 634 286. In this method ethoxymethylideneacetoacetic ester is reacted with hydroxylamine to form the 5methylisoxazole - 4 - carboxylic acid ester, the ester is hydrolysed under acid conditions, preferably with a mixture of glacial acetic, acid and concentrated hydrochloric acid in the ratio 1:1, and the 5- methylisoxazole - 4 - carboxylic acid formed is converted according to a customary method into a carboscylic acid halide, ester or mixed anhydride.
The following are examples of carboxylic acid derivatives of the general formula II: - methylisoxazole - 4 - carboxylic acid phenyl esters, especially the 2,4 - dichlorophenyl ester of the 2,4 6-trichlorophenyl ester; and - methylisoxazole - 4 - carboxylic acid anhydrides, especially those in which X represents the methoxycarbonyloxy radical, the ethoxycarbonyloxy radical, the phenoxycarbonyloxy radical or the benzyloxycarbonyloxy radical.
The compounds according to the invention of the general formula I are generally substances that are readily crystallisable. They may be converted into acid addition salts, preferably physiologically tolerable acid addition salts, for example with strong acids, e.g. hydrohalic acids, especially hydrochloric acid, sulphuric acid, phosphoric acid, p-toluene25 sulphonic acid, methanesulphonic acid or cyclohexylamidosulphonic acid.
The 5 - methylisoxazole - 4 - carboxylic acid amides of the general formula I and their physiologically tolerable salts have useful pharmacological properties. In particular they exhibit antiphlogistic, antipyretic and analgesic - 8 46^69 properties. Their toxicity is low, and their compatibility with the stomach is good.
Accordingly, the present invention provides a pharmaceutical preparation, which comprises a compound of the general formula I or a physiologically tolerable salt thereof, in admixture or conjunction with a pharmaceutically suitable carrier. Preferably the preparation is in dosage unit form.
The following Examples illustrate the invention. 1.
