Reaction Steps

To a stirred solution of 4-chloro-5,7-difluoro-2-(6-fluoropyridin-3-yl)-3-methylquinoline (0.10 g, 0.32 mmol) in DMF (2 mL) was added 4,4-difluoropiperidine hydrochloride (0.056 g, 0.36 mmol) followed by potassium carbonate (0.090 g, 0.65 mmol). The reaction was stirred at 100° C. and stirring continued for 66.5 h. After which, the reaction mixture was cooled to rt and water was added. The crude reaction mixture was extracted with EtOAc and 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-2-(6-(4,4-difluoropiperidin-1-yl)pyridin-3-yl)-5,7-difluoro-3-methylquinoline as a brown solid. Mass Spectrum (ESI) m/e=410.0 (M+1).
