| abstract |
The present invention relates to compounds corresponding to formula (I) in which: - R 1 represents a substituted phenyl; - R 2 represents: - a substituted phenyl; - a heteroaromatic group, the said group being unsubstituted or substituted one or more times; - R 3 represents a group Alk; - R 4 represents a hydrogen atom or a (C 1 -C 4 )alkyl; - R 5 represents a hydrogen atom, a (C 3 -C 6 )cycloalkyl or a (C 1 -C 4 )alkyl-O-Alk; - or alternatively R 4 and R 5 , together with the nitrogen atom to which they are attached, constitute a heterocyclic radical chosen from: azetidin-1-yl, pyrrolidin-1-yl, piperid-1-yl, morpholin-4-yl; - R 6 represents a group -COOAlk, a group -CONH 2 or a group -NHSO 2 Alk; - Alk represents a (C 1 -C 4 )alkyl, which is unsubstituted or substituted one or more times with a halogen atom; in the form of the base or of an acid-addition salt.
