Reaction Steps

2,4-dichloro-5,7-difluoro-3-methylquinoline (1.50 g, 6.20 mmol), XantPhos (540 mg, 0.93 mmol), 4,4-dimethylpyrrolidin-2-one (700 mg, 6.20 mmol), cesium carbonate (2.80 g, 8.70 mmol), 3 A activated molecular sieves (1.0 g) and Pd2(dba)3 (280 mg, 0.31 mmol) were slurried in 1,4-dioxane (21 mL). The reaction was heated in an oil bath at 100° C. for 1 h. After this time the reaction was cooled to rt, diluted with EtOAc and filtered over a pad of Celite™. The filtrate was concentrated and the residue was purified by column chromatography (silica gel, 0 to 30% EtOAc:DCM as eluant) to give 1-(4-chloro-5,7-difluoro-3-methylquinolin-2-yl)-4,4-dimethylpyrrolidin-2-one. Mass Spectrum (ESI) m/e=325.1 (M+1).
