Cyclization of 1-hydrazinyl-3,3-dimethyl-3,4-tetrahydro-5 H -benzo c azepine with ethyl orthoformate gave 5,5-dimethyl-6,7-dihydro-5 H benzo c -1,2,4-triazolo3,4- a azepine, and its reaction with acetic acid afforded 3,5,5-trimethyl-9,10-dimethoxy-6,7-dihydro-5 Н -benzo c -1,2,4-triazolo3,4- a azepine. Nitrosation of 1-hydrazino-3,3-dimethyl-3,4-tetrahydro-5 H -benzo c azepine led to the formation of substituted 6,7-dihydro-5 H -benzo c tetrazolo5,1- a azepines.
