Abstract

Abstract Eight new benzotriazoloazepine derivatives have been synthesized starting from 7- methoxy-2, 3, 4, 5-tetrahydro-1H-2-benzo [c] azepin-1-one. The compounds 2a–c have been synthesized by the reaction of 7-methoxy-2, 3, 4, 5-tetrahydro-1H-2-benzo [c] azepin-1- thione with various hydrazides. Reaction of 5 with hydrazine hydrate, followed by treatment of the resultant hydrazone with formic acid, gave corresponding 9-alkoxy-6, 7-dihydro-5H- ...
