Procedure

A biphasic solution of 6-acetyl-4-chloro-2-cyano-3-methylphenyl trifluoromethanesulfonate (2.54 g, 7.4 mmol) and (3-fluorophenyl)boronic acid (1.6 g, 11 mmol) in toluene (70 mL) and saturated sodium bicarbonate (70 mL) was bubbled with N2 to degas. After tetrakis(triphenylphosphine)palladium(0) (0.43 g, 0.37 mmol) was added, the mixture was bubbled with N2 for 5 min more and then heated at 80° C. for 2 hours. After cool to room temperature, the mixture was diluted with ethyl acetate. The layers were separated and the aq. layer was extracted with more ethyl acetate. The combined extracts were washed with brine, dried over Na2SO4, filtered, and concentrated. The residue was purified on silica gel column, eluting with 0 to 40% ethyl acetate in hexane, to give the desired product (2.1 g, 99%). LCMS calculated for C16H12ClFNO (M+H)+: m/z=288.1. found: 288.1.
