XantPhos (273 mg, 0.472 mmol), 2,4-dichloro-5,7-difluoro-3-methylquinoline (780 mg, 3.20 mmol), 5,5-dimethylpiperidin-2-one (400 mg, 3.20 mmol), cesium carbonate (1.40 g, 4.40 mmol) and Pd2(dba)3 (140 mg, 0.160 mmol) was slurried in 1,4-dioxane (8.5 mL) and heated in a microwave reactor at 100° C. for 3 h. The reaction was cooled to rt and then diluted with EtOAc and DCM. The slurry was then filtered and concentrated. The residue was purified by column chromatography (silica gel, 0 to 50% EtOAc:DCM) to give 1-(4-chloro-5,7-difluoro-3-methylquinolin-2-yl)-5,5-dimethylpiperidin-2-one. Mass Spectrum (ESI) m/e=339.1 (M+1).
