To a stirred solution of 2,4-dichloro-5,7-difluoro-3-methylquinoline (0.17 g, 0.685 mmol) in toluene (1.40 mL) was added 3-methyl-2-(tributylstannyl)pyridine (0.29 g, 0.75 mmol), and palladium tetrakistriphenylphosphine (0.079 g, 0.069 mmol). The reaction was stirred at 100° C. and stirring continued for 68 h. The reaction mixture was cooled to rt and concentrated in vacuo. The crude material was purified by column chromatography on silica gel, eluting with (0-50% EtOAc in hexanes) to provide 4-chloro-5,7-difluoro-3-methyl-2-(3-methylpyridin-2-yl)quinoline as a white solid. Mass Spectrum (ESI) m/e=305.0 (M+1).
