<p>Compounds represented by the following general formula (I):$(7,)$wherein R1 represents a hydrogen atom, a hydroxy group, a lower alkyl group or a lower alkoxy group, R2 represents a hydrogen atom, a benzoyl group or$(3,)$R3 represents a hydroxy group, a lower alkoxy group, -NHOH or$(5,)$R5 represents a hydrogen atom or a halogen atom, R?6 and R7¿, which may be the same or different, each represents a hydrogen atom or a lower alkyl group, and Z represents a C¿1? to C3 straight or branched alkylene group, provided that when R?3¿ represents a hydroxy group or a lower alkoxy group, R2 represents$(3,)$with said lower alkyl group and lower alkoxy group containing 1 to 6 carbon atoms. Process for their preparation, and hypotensives containing the compounds as major component.</p> |
