摘要

The invention concerns compounds of formula (I) in which in particular, R1 represents R'1, OR'1, SR'1, NHR'1, COR'1, CHOHR'1, CH2R'1, in which R'1 represents an aryl radical selected among a phenyl, a naphthyl or a pyridyl; R2 represents a halogen (Cl, F, Br), OH, NH2, CN, NO2, R'2, OR'2, SR'2, NHR'2, COR'2, CHOHR'2, COOR'2, NHCOR'2, NHCOOR'2, NHSO2R'2, OCONHR'2, in which R'2 represents an alkyl chain linear or branched, an aryl or an arylalkyl; Z represents CO-(CH2)n-O, CO-(CH2)n-NH, (CH2)m-O,(CH2)m-NH, CO-(CH2)p-CONH-, (CH2)p-CONH, CO-(CH2)p-NHCONH-, (CH2)m-NHCONH, -CO(CH2)p-OCONH-, (CH2)m-OCONH, -CO(CH2)p-NHCOO, (CH2)m-NHCOO, in which n represents zero or a whole number ranging between 1 and 8, m represents a whole number ranging between 2 and 8 and p represents a whole number ranging between 1 and 8; Ar represents an aromatic radical such as a phenyl or a naphthyl; R3 represents an alkyl radical linear or branched containing 1 to 6 carbon atoms: These compounds are particularly useful as antidepressant drugs.
