Reaction Steps

To a stirred solution of 4-chloro-5,7-difluoro-2-(6-fluoropyridin-3-yl)-3-methylquinoline (0.1 g, 0.324 mmol) in dmf (0.025 mL, 0.32 mmol) was added 1-methylpiperazine (0.036 g, 0.356 mmol) followed by potassium carbonate (0.090 g, 0.65 mmol). The reaction was stirred at 80° C. and stirring continued for 19 h. After which, the reaction mixture was cooled to rt and water was added. The crude reaction mixture was extracted with EtOAc, dried over magnesium sulfate and concd in vacuo. The crude material was purified on silica gel, eluting with 0-30% EtOAc in hexanes to provide 4-chloro-5,7-difluoro-3-methyl-2-(6-(4-methylpiperazin-1-yl)pyridin-3-yl)quinoline as a white solid. Mass Spectrum (ESI) m/e=389.1 (M+1).
