Procedure

Use a method similar to the General Procedure 5-3, react 7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (250 mg, 0.588 mmol) with 4-aminomethyl-N-(2-thiophen-2-yl-ethyl)-benzamide (306 mg, 1.176 mmol) using palladium(II) acetate (26 mg, 0.118 mmol), tris(dibenzylideneacetone)dipalladium(0) (53 mg, 0.059 mmol), BINAP (220 mg, 0.353 mmol) and cesium carbonate (383 mg, 1.176 mmol) in dioxane (6 mL). Purify by chromatography on silica gel eluting with hexane/EtOAc (1:0, 7:3 and 1:1) to give 7-chloro-6-{4-[(2-thiophen-2-yl-ethyl)-carbamoyl]-benzylamino}-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as an oil (233 mg, 91%). MS (ES+) m/z: 535 (M+H)+.
