Derivatives of (1h-imidazol-4-yl) piperidine, their preparation and their application in therapeutic
1997
The invention concerns compounds of formula (I) in which R1 and R2 represent each independently of each other either a hydrogen atom, or a (C1-C4) linear or branched alkyl group; R3 and R4 represent each independently of each other either a hydrogen or halogen atom, or (C1-C4) alkyl group, trifluoromethyl, (C1-C4) alkoxy, S(O)pR with R a (C1-C4) linear or branched alkyl group and p = 0 to 2; and A represents either a hydrogen atom, or a (C1-C6) linear or branched alkyl group, phenyl (C1-C4)alkyl, -COR5, -COOR5, -CONHR5, -SO2R5, where R5 is a (C1-C6) linear or branched alkyl group, a (C3-C7) cycloalkyl group; a (C3-C7) cycloalkyl (C1-C5)alkyl group, a (C1-C4) alkoxy (C1-C6) alkyl group, a phenyl group, a phenyl (C1-C4) alkyl group, a phenyl (C1-C4)alkylidene group, or a -COCH2NR6R7 group where R6 is a hydrogen atom or a (C1-C4) linear or branched alkyl group and R7 a (C1-C4) linear or branched alkyl group or acyl or R1, R3 and R4 being such as defined above, A and R2 form a cycle of the type -(CH2)nCO- where n can take a value between 2 and 6, in the form of pharmaceutically acceptable free bases or addition salts to acids The invention is applicable in therapy.
