Abstract

Several 4,5‐dihydro‐4‐phenyl‐3H‐1,3,4‐benzotriazepines were synthesized by conversion of 1‐[(2‐nitrophenyl)methyl]‐1‐phenylhydrazine to either 1‐[(2‐aminophenyl)methyl]‐1‐phenylhydrazine or 1‐[(2‐aminophenyl)‐methyl]‐2‐methyl‐1‐phenylhydrazine. Ring closure of these intermediates with triethyl orthoacetate or triethyl orthopropionate gave the title compounds in overall yields of 40‐60%.
