Reaction Steps

Use a method similar to the General Procedure 5-3 to react 7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (541 mg, 1.274 mmol), palladium(II) acetate (57 mg, 0.225 mmol), tris(dibenzylideneacetone)dipalladium(0) (117 mg, 0.127 mmol), BINAP (0.506 g, 0.764 mmol), 2,2-difluoro-2-phenyl-ethylamine (400 mg, 2.547 mmol) and cesium carbonate (830 mg, 2.548 mmol) in degassed toluene (35 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 filter over Celite®. Purify the crude mixture by chromatography on silica gel eluting with hexane and hexane/EtOAc (19:1) to obtain 7-chloro-6-(2,2-difluoro-2-phenyl-ethylamino)-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as oil (335 mg, 61%). MS (ES+) m/z: 433 (M+H)+.
