Reaction Steps

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 (127 mg, 0.3 mmol) with 4-(3,3-dimethyl-butyryl)-2-fluoro-benzylamine (120 mg, 0.54 mmol) by using tris(dibenzylideneacetone)dipalladium(0) (27 mg, 0.03 mmol), BINAP (40 mg, 0.06 mmol) and cesium carbonate (137 mg, 0.42 mmol) in anhydrous toluene (20 mL). Purify by chromatography on silica gel eluting with hexane/EtOAc (19:1 and 9:1) followed by reverse phase HPLC [Zorbax Bonus RP, 5 □M 21.2×100 mm, eluting with water/acetonitrile (0.05% TFA in each) (35:65 to 15:85 gradient over 5 min), flow rate 25 mL/min, UV detector (230 nm)] to give 7-chloro-6-[4-(3,3-dimethyl-butyryl)-2-fluoro-benzylamino]-3-(2,2,2-trifluoroacetyl)-2,3,4,5-tetrahydro-1H-benzo[d]azepine as an oil (72 mg, 49%). MS (ES+) m/z: 499 (M+H)+.
