Patent ID: 7115780

Claim:
A compound of formula (I): in which: A is a group of formula (a) or (b) where R represents a hydrogen or halogen atom, an —S(O) 2 (C 1 –C 4 )alk group where z is 0, 1 or 2, an —NHSO 2 (C 1 –C 4 )alk, —SO 2 NH(C 1 –C 4 )alk, —NHSO 2 —(C 1 –C 4 )alk-phenyl or —NHSO 2 -phenyl group, it being possible for said phenyl to carry a halogen atom, a (C 1 –C 4 )alk group or a (C 1 –C 6 )alkoxy group; R 1 represents a hydrogen atom or a —(C 1 –C 4 )alk, —CO(C 1 –C 4 )alk, —(C 1 –C 4 )alk-phenyl or —CO-phenyl-group, it being possible for said phenyl to carry a halogen atom or a —(C 1 –C 4 )alk or (C 1 –C 6 )alkoxy group; R 2 is a hydrogen atom, an —SO 2 (C 1 –C 4 )alk, —SO 2 —(C 1 –C 4 )alk-phenyl, —SO 2 -phenyl, or a —(C 1 –C 4 )alk group; X completes a saturated or unsaturated 5- to 8-atom ring which can carry one or two —(C 1 –C 4 )alk groups and/or one or two carbonyl groups; R 3 and R′ 3 each represent independently a hydrogen or halogen atom, a —(C 1 –C 6 )alk, hydroxyl, —CN, —(C 1 –C 6 )alkoxy, —COR 4 or —Y—CR 8 R 9 —COR 4 group; Y represents O or CH 2 ; R 4 represents a hydroxyl, (C 1 –C 6 )alkoxy or —NR 5 R 6 group; R 5 and R 6 represent independently a hydrogen atom; a —(C 1 –C 4 )alk, aryl or heteroaryl group optionally substituted with an R 7 group, an aralkyl or heteroaralkyl group optionally substituted with an R 7 group; or else R 5 and R 6 , with the nitrogen atom carrying them, form a saturated or unsaturated 5- to 7-atom ring optionally substituted with an R 7 group; R 7 represents a hydrogen or halogen atom, a hydroxyl, —(C 1 –C 4 )alk, —(C 1 –C 6 )alkoxy, —NH(C 1 –C 4 )alk, —N(C 1 –C 4 )alk 2 , —COO(C 1 –C 4 )alk, aralkyl or heteroaralkyl group; and R 8 and R 9 represent independently a hydrogen atom or a —(C 1 –C 4 )alk group; or a salt thereof.
