Patent ID: 7625929

Claim:
A compound corresponding to formula (I): wherein: R 1 is a hydrogen atom; R 2 is an —S(O) z R 3 group, or an —NHSO 2 R 3 group, where z is equal to 2 and where R 3 is a (C1-C4)alkyl group; and A is wherein: n is equal to 0, 1 or 2, and R 4 and R 5 are carried either by different carbon atoms, or by the same carbon atom of the ring to which they are attached, and are chosen independently of each other from the following groups: a hydrogen atom, a (C1-C4)alkyl, hydroxyl, cyano, phenyl, benzyl, piperidyl, —CONH 2, —CO-phenyl, —COOR 3 (where R 3 is as defined above), —CH(phenyl)(OH) and —C(phenyl) 2 (OH) group, at least one of R 4 or R 5 being different from a hydrogen atom, or R 4 and R 5 are carried by adjacent carbon atoms of the ring to which they are attached and form together with the carbon atoms carrying them a 6-membered aromatic ring optionally substituted with 1 to 3 (C1-C4)alkyl or (C1-C4)alkoxy groups, or an addition salt with acid thereof.
