Reaction Steps

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 (200 mg, 0.47 mmol) with (±)-1-thiophen-3-yl-ethylamine (prepared as described in J. Heterocycl. Chem. 1988, 25, 1571-1581) (90 mg, 0.70 mmol). Purify by chromatography on silica gel eluting with hexane/EtOAc (1:0, 9:1 and 4:1) to give (±)-7-chloro-6-(1-thiophen-3-yl-ethylamino)-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine (100 mg, 53%).
