ABSTRACT:
Benzocycloheptapyridines with an imine bridge in the cycloheptane ring, derivatives and pharmaceutically acceptable salts thereof are useful as anxiolytics, antidepressants, anticonvulsants, muscle relaxants and in the treatment of mixed anxiety-depression, minimal brain dysfunction and extrapyramidal disorders such as Parkinson's disease. They are prepared, for example, by treatment of a benzo[5,6]cyclohepta[1,2-c]pyridin-11-one with ammonia to give the 11-imine, acylation of the imine, treatment of the protected imine with an alkyllithium to provide the 11-alkyl-11-acylamino compound, treatment with acid or base to cause ring closure to an 11-alkyl-6,11-acylimino compound followed by removal of the protecting group, either hydrolytically or hydrogenolytically.
