Procedure

Under a nitrogen atmosphere, to a solution of ethyl 3-cyclopropyl-3-(3-(((2′-fluoro-5′-methoxy-2-(((trifluoromethyl)sulfonyl)oxy)biphenyl-4-yl)oxy)methyl)phenyl)propanoate (173 mg) in toluene (5.0 mL) were added 4-(trifluoromethyl)phenylboronic acid (157 mg), tris(dibenzylideneacetone)dipalladium(0) (20 mg), 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (39 mg) and 2.0 M aqueous sodium carbonate solution (0.43 mL), and the mixture was stirred at 90° C. for 15 hr. The reaction mixture was filtered through celite, water was added to the filtrate, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (97 mg) as a colorless oil.
