Patent ID: 8912218

Claim:
Compound of the formula (I) in which R 2 represents a hydrogen or fluorine atom, a hydroxyl, cyano, trifluoromethyl, C 1-6 alkyl or C 1-6 alkoxy group or a group NR 8 R 9 ; n represents an integer 2 and m represents an integer 2; A represents a covalent bond or a C 1-8 alkylene group; R 1 represents a group R 5 which is optionally substituted by one or more groups R 6 and/or R 7 ; R 5 represents a pyridinyl group; R 6 represents a halogen atom, a cyano, —CH 2 CN, nitro, hydroxyl, C 1-6 alkyl, C 1-6 alkoxy, C 1-6 thioalkyl, C 1-6 haloalkyl, C 1-6 haloalkoxy, C 1-6 halothioalkyl, C 3-7 cycloalkyl, C 3-7 cycloalkyl-C 1-3 alkylene or C 3-7 cycloalkyl-C 1-3 alkylene-O— group, or a group NR 8 R 9 , NR 8 COR 9 , NR 8 CO 2 R 9 , NR 8 SO 2 R 9 , NR 8 SO 2 NR 8 R 9 , COR 8 , CONR 8 R 9 , SO 2 R 8 , SO 2 NR 8 R 9 or —O—(C 1-3 -alkylene)-O—; R 7 represents a group selected from a thienyl, isoxazolyl, pyrazolyl, phenyl, pyridinyl, pyrimidinyl, naphthalenyl, quinolinyl or isoquinolinyl, the group or groups R 7 being able to be substituted by one or more groups R 6 which are identical or different from one another; R 3 represents a hydrogen or fluorine atom, a C 1-6 alkyl group or a trifluoromethyl group; R 4 represents a thiazole which is optionally substituted by one or more substituents selected from a C 1-6 alkyl and CONR 8 R 9 ; R 8 and R 9 represent independently of one another a hydrogen atom or a C 1-6 alkyl group, or form, with the atom or atoms bearing them, in the case of NR 8 R 9 , a ring selected from azetidine, pyrrolidine, piperidine, morpholine, thiomorpholine, azepine, oxazepine or piperazine ring, this ring being optionally substituted by a C 1-6 alkyl or benzyl group; in the case of NR 8 COR 9 , a lactam ring; in the case of NR 8 CO 2 R 9 , an oxazolidinone, oxazinone or oxazepinone ring; in the case of NR 8 SO 2 R 9 , a sultam ring; in the case of NR 8 SO 2 NR 8 R 9 , a thiazolidine dioxide or thiadiazinane dioxide ring; in the form of the base or an addition salt with an acid.
