To a mixture of 7-acetyl-5-methylquinolin-8-yl trifluoromethanesulfonate (0.833 g, 2.50 mmol) in tetrahydrofuran (20 mL), with stirring, was added 0.5 M (3-fluorophenyl)(iodo)zinc in THF (10.0 mL, 5.0 mmol), followed by tetrahydrofurantetrakis(triphenylphosphine)palladium(0) (289 mg, 0.250 mmol). The reaction mixture was heated at 60° C. overnight, cooled to room temperature and quenched with sat. sodium bicarbonate. The mixture was filtered through a Celite pad. The filtrate was extracted with ethyl acetate. The combined organic layers were washed with brine, dried and concentrated under reduced pressure. The residue was purified on silica gel, eluting with 0 to 80% ethyl acetate in hexane, to give the desired product (0.379 g, 54%). LCMS calculated for C18H14FNO (M+H)+: m/z=280.1; Found: 280.0.
