A (C1-C4) alkyl, (C3-C6) cycloalkylmethyl or phenyl (C1-C3) optionally substituted in the phenyl ring with one or more atoms or groups selected from halogens and methyl, trifluoromethyl, methoxy, and cyano groups. ) an alkyl group or a hydrogen atom, R2 is a hydroxyl or alkoxy group, or R3 and R4 are a hydrogen atom, an alkyl group, a cycloalkyl group, a cycloalkylmethyl group, a phenyl group, a phenylmethyl group, or a pyridinyl group. Compounds denoted as the general formula (I), which represents or alternatively together with the nitrogen atom, R3 and R4 form a pyrrolidine or piperidine ring, the general formula of which is NR3R4 and the number n is 1, 2 or 3. |
