Procedure

Use a method similar to the General Procedure 5-1 to react 7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (623 mg, 1.46 mmol), palladium(II) acetate (33 mg, 0.146 mmol), BINAP (182 mg, 0.292 mmol), 4-(3,3-dimethyl-butyl)-benzylamine (560 mg, 2.93 mmol) and cesium carbonate (666 mg, 2.04 mmol) in degassed toluene (40 mL). Degas the mixture with vacuum/nitrogen purge and heat to 100° C. for 16 h. Cool the mixture to room temperature, dilute with EtOAc and wash with water. Dry the organic phase over MgSO4, filter and concentrate in vacuo. Purify the crude mixture by chromatography on silica gel eluting with hexane and then hexane/EtOAc (19:1, 9:1) to obtain 7-chloro-6-[4-(3,3-dimethyl-butyl)-benzylamino]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as oil (622 mg, 91%). MS (ES+) m/z: 467 (M+H)+.
