The synthesis of some 7‐ and 7,8‐substituted 2,3,4,5‐tetrahydro‐1H‐3‐benzazepines

Abstract

The nitration of 2,3,4,5‐tetrahydro‐1H‐3‐benzazepine and its 3‐methyl and 3‐acetyl derivatives yields the corresponding 7‐nitro derivatives which can be further transformed by classical procedures. The preparation of the ether cleavage products of the known 2,3,4,5‐tetrahydro‐7,8‐dimethoxy‐1H‐3‐benzazepine is also reported.
