Compound corresponding to the formula I: in which: may adopt a value from 1 to 6 - (C) n-represents a -C1-6 alkylidene group, optionally substituted by 1 to 4 substituents; -R1 represents . a hydrogen atom , . a C1-6 alkyl group R2 represent . a hydrogen atom, . a C1-6 alkyl or C3-6 cycloalkyl group ,each of which is optionally substituted by 1 to 4 substituents; B represents . NR3R4, -where R3 and R4 represent, independently of one another, a C1-6 alkyl group or a hydrogen atom, or R3 and R4 together represent a C1-6 alkylidene, a group aC2-8 alkenylidene group, a C1-3 alkylidene-O-C1-3 alkylidene group or a C1-3 alkylidene-N (R5)-C1-3 alkylidene in which R5 represents a hydrogen atom, a C1-3 alkyle or C1-6 alkylcarbonyl group, it being possible for there C1-3 alkyle and C1-6 alkylcarbonyl group to be substituted, or . a cyclic amino,bonded via a carbon to the group-NR1-(C) n- such as aziridine, azetidine, pyrrolidine, piperidine or morpholine; The groups R3 and R4, and the cyclic amino being optionally substituted and the nitrogen atom being optionally substituted.
