Reaction Steps

A stirred mixture of 5-chloro-7-{[methoxy(methyl)amino]carbonyl}quinolin-8-yl trifluoromethanesulfonate (0.150 g, 0.376 mmol), (2R)-2-(methoxymethyl)pyrrolidine (0.0521 g, 0.452 mmol, Fluka), palladium acetate (2 mg, 0.008 mmol), 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (7 mg, 0.01 mmol), and cesium carbonate (0.343 g, 1.05 mmol) in tetrahydrofuran (4 mL) was heated at 65° C. overnight. The mixture was cooled, diluted with dichloromethane, and filtered. The filtrate was washed with brine, dried over sodium sulfate, and evaporated to dryness. The resultant residue was purified on silica gel, eluting with 0 to 10% MeOH in dichloromethane, to give the desired product (132 mg, 96%). LCMS calculated for C18H23ClN3O3(M+H)+: m/z=364.1; found: 364.1.
