7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethylsulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine 、
4-[N-(tert-butoxycarbonyl)-N-(cyclohexyl)-aminomethyl]-benzylamine 在
silica gel 、
ethyl acetate n-hexane 作用下,
以to obtain 6-{-4-[N-(tert-butoxycarbonyl)-N-(cyclohexyl)-aminomethyl]-benzylamino}-7-chloro-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (320 mg, 76%)的产率得到6-{-4-[N-(tert-butoxycarbonyl)-N-(cyclohexyl)-aminomethyl]-benzylamino}-7-chloro-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine
