The invention concerns compounds of formula (I) in which R1 and R'1 represent hydrogen, halogen or (C1-C4) alkyl, R2 represents a piperidin-1-yl group, 1, 2, 3, 6-tetrahydropyridin-1-yl optionally substituted, hexahydro-1H-azepin-1-yl, heptahydroazocin-1-yl, octahydro-1H-azonin-1-yl, (a) (A-B = -CONR", m = 1 to 2 and p = 1 to 2), (b) (Q = carbon or nitrogen, D = (C1-C4) alkyl or -CH2CF3, and r = 1 to 3, R3 represents (C1-C5) alkyl, -COR5 [R5 being (C1-C4) alkyl, -(CH2)nOCH3, -CH2O(C2H4O)nCH3, -(CH2)nCF3, -(CH2)nOH (n = 1 to 4)], -SO2R6, -CONHR6, -SO2N(R6)2 (R6 being (C1-C4) alkyl), R4 represents hydrogen or halogen and A represents phenyl or heterocycle optionally substituted or cyclo (C5-C8) alkyl. The invention is applicable in therapeutics. |
