1-Benzoyl-4-aminoacyl-7-phenyl-1,4-diazepine derivatives (I) are new. Also new are four classes of intermediates. 1,4-Diazepine derivatives of formula (I) and their acid addition salts are new. Ph1 = phenyl substituted by R2 and R3; Ph2 = phenyl substituted by R4 and R5; Ph3 = 3-(R6)-5-(R7)-phenyl; R1 = H or alkyl; R2-R5 = H, alkyl, alkoxy, halo or CF3; or R2+R3 or R4+R5 on adjacent C = 1-2C alkylenedioxy; R6,R7 = alkyl, halo or CF3; A = (CH2)n or NH(CH2)m; n = 1-3; m = 2 or 3; and B = 1-3C alkylene chain (optionally substituted by alkyl). |
