This invention relates to substituted-1,3,4-benzotriazepines of the formula
wherein X and Y are each independently hydrogen, lower alkyl, halogen, lower alkoxy, nitro and hydroxyl; R1 and R3 are each independently hydrogen or alkyl; R2 is hydrogen, lower alkyl, cycloalkyl lower alkyl, phenyl, aryl lower alkyl, hydroxyl and sulfhydryl; m and n are each independently integers of 0 or 1 and when m is 0, n is 1 and vice-versa; and p and q are independently integers of 1 or 2. Also included in the invention are the substituted-1,3,4-benzotriazepine derivatives of tautomeric form when the substituent for R, and or R3 in the above formula is hvdrogen.
The invention relates further to a process for the preparation of the mentioned compounds and their use as antihypertensive agents.
本发明涉及式中的取代-1,3,4-苯并三氮杂卓
其中X和Y各自独立地为氢、低级烷基、卤素、低级烷氧基、硝基和羟基;R1和R3各自独立地为氢或烷基;R2为氢、低级烷基、环烷基低级烷基、苯基、芳基低级烷基、羟基和巯基;m和n各自独立地为0或1的整数,当m为0时,n为1,反之亦然;p和q各自独立地为1或2的整数。本发明还包括当上式中 R 和或 R3 的取代基为 hvdrogen 时的同分异构形式的取代-1,3,4-苯并三氮杂卓衍
