Reaction Steps

A screw-cap vial was charged with 4-chloro-3-(trifluoromethoxy)benzaldehyde (available from Alfa Aesar, Avocado, Lancaster) (0.184 g, 0.82 mmol), 2-fluoro-5-methoxyphenylboronic acid (available from Aldrich) (0.278 g, 1.64 mmol), potassium phosphate (0.522 g, 2.46 mmol), 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (0.101 g, 0.25 mmol), palladium(II) acetate (0.018 g, 0.082 mmol), and 5:1 THF/DMF (3.6 mL). The mixture was stirred overnight at 40° C., cooled to room temperature, diluted with EtOAc, washed with water and brine, dried (MgSO4), and concentrated. The crude product was chromatographed on silica gel (0-10% EtOAc/hexane) to afford 46.1 (165 mg, 64%) as a colorless oil.
