Use a method similar to the General Procedure 5-3 to couple 7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (400 mg, 0.94 mmol) and (±)-1-pyridin-4-yl-ethylamine (prepared as described in Bull. Kor. Chem. Soc. 1998, 19 (8), 891-893) (172 mg, 1.41 mmol). Purify by chromatography on silica gel eluting with hexane/EtOAc (1:0, 4:1 and 1:1) to give (±)-7-chloro-6-[(1-pyridin-4-yl-ethyl)-amino]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine.
