<p>The present invention relates to compounds having the general formula: (I) in which n1 and R2, which may be the same or different, represent each a hydrogen atom, a C1-C6 alkyl radical or a C3-C6 cycloalkyl radical; R3 represents a hydrogen atom or a C1-C4 alkyl radical; R4 and R5, which may be the same or different, represent a hydrogen atom, a C1-C6 alkyl radical or, together with the nitrogen atom to which they are attached, form a pyrrolidino, piperidino, morpholino or piperazinyl radical optionally substituted with a C1-C4 alkyl radical, or a 4-hydroxy-piperidino radical, and their pharmaceutically acceptable acid eddition salts. Said compounds are therapeutically useful for the control of the cardio-vascular system and of the blood pressure.</p> |
