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%.
通过将1-[((2-硝基苯基)甲基] -1-苯基肼转化为1-[(2-氨基苯基)甲基]合成了几种4,5-二氢-4-苯基-3H-1,3,4-苯并三氮杂s ] -1-苯基肼或1-[((2-氨基苯基)-甲基] -2-甲基-1-苯基肼。用原乙酸三乙酯或原丙酸三乙酯将这些中间体闭环,得到标题化合物,总收率为40-60%。
