Procedure

Use a method similar to the General Procedure 5-2 to couple 7-chloro-3-(2,2,2-trifluoroacetyl)-6-trifluoromethanesulfonyloxy-2,3,4,5-tetrahydro-1H-benzo[d]azepine (1.24 g, 2.91 mmol) with methyl 4-aminomethyl-2-fluoro-benzoate (1.065 g, 5.821 mmol) by using tris(dibenzylideneacetone)dipalladium(0) (0.533 g, 0.582 mmol), BINAP (0.725 g, 1.16 mmol) and cesium carbonate (3.32 g, 10.2 mmol) under nitrogen in anhydrous toluene (20 mL). Purify by chromatography on silica gel eluting with hexane/EtOAc (19:1 to 1:1 gradient over 71 min; 50 mL/min) to afford the desired intermediate as a yellow oil (1.3 g, 100%).
