7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethylsulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine 、
(R)-4-[(1-methyl-2,2,2-trifluoro-ethylcarbamoyl)-methyl]-benzylamine 在
silica gel 、
ethyl acetate n-hexane 作用下,
以to obtain (R)-7-chloro-6-{4-[(1-methyl-2,2,2-trifluoro-ethylcarbamoyl)-methyl]-benzylamino}-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as a yellow oil (47 mg, 45%)的产率得到(R)-7-chloro-6-{4-[(1-methyl-2,2,2-trifluoro-ethylcarbamoyl)-methyl]-benzylamino}-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine
