Procedure

Compound 7B (20 mg, 0.058 mmol), 4-bromobenzonitrile (16 mg, 0.088 mmol), tris(dibenzylideneacetone)dipallidium (2.1 mg, 0.0023 mmol), racemic-2,2′- bis(diphenylphosphino)-1,1′-binaphthyl (BINAP) (2.2 mg, 0.0035 mmol), cesium carbonate (29 mg, 0.088 mmol) and toluene (1 mL) were mixed and heated at 100° C. overnight. The reaction mixture was cooled, quenched with water, and extracted with dichloromethane 3×. Combined organic layer was dried over sodium sulfate, filtered and concentrated to give the crude product, which was then purified on silica gel column which was eluted with 0.3% ammonium hydroxide and 3% methanol in dichloromethane to give the desired product (12 mg, 46% yield).
