To a solution of sodium hydrogenecarbonate (0.049 g, 0.58 mmol) in water (1 mL) was added a solution of 1-(6-bromo-4-chloro-3′-fluoro-5-methylbiphenyl-2-yl)ethanone (0.10 g, 0.29 mmol) in toluene (1 mL) followed by 1-(1-ethoxyethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (0.093 g, 0.35 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.017 g, 0.015 mmol). The resulting mixture was bubbled with N2 for 5 min and then heated at 80° C. over a weekend. The organic layer was concentrated and purified on silica gel (eluting with 0-30% of ethyl acetate in hexanes) to give the desired product (37 mg, 32%). LCMS calculated for C22H23ClFN2O2 (M+H)+: m/z=401.1. found: 401.1.
