| abstract |
The invention relates to derivatives having general formula (I), in which: X represents an optionally substituted phenyl group; R1 represents a hydrogen atom, a halogen, an optionally substituted (C1-C6)alkoxy group, an optionally substituted (C1-C6)alkyl group, a (C3-C7)cycloalkyl(C1-C6)alkyl group, a (C3-C7)cycloalkyl(C1-C6)alkoxy group, a hydroxy, an amino; R2 represents a hydrogen atom, an optionally substituted (C1-C6)alkyl group, an optionally substituted (C1-C6)alkoxy group, a (C3-C7)cycloalkyl(C1-C6)alkyl group, a (C3-C7)cycloalkyl(C1-C6)alkoxy group, a (C2-C6)alkenyl group, a (C2-C6)alkynyl group, a -CO-R5 group, a -CO-NR6R7 group, a -CO-O-R8 group, a -NR9-CO-R10 group, a -NR11R12 group, a halogen atom, a cyano group or an optionally substituted phenyl group; R3 represents a hydrogen atom, a (C1- C6)alkyl group or a halogen atom; and R4 represents a hydrogen atom or a halogen atom, said derivatives taking the form of a base or an acid addition salt. The invention also relates to the preparation method thereof and to the use of same in therapeutics. |
