Reaction Steps

A stirred mixture of 7-acetyl-5-chloroquinolin-8-yl trifluoromethanesulfonate (0.106 g, 0.301 mmol, from Example 47, Step 2), (3S)-piperidin-3-ol hydrochloride (0.0498 g, 0.362 mmol), palladium acetate (1 mg, 0.006 mmol), (S)-(−)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (6 mg, 0.009 mmol), and cesium carbonate (0.274 g, 0.843 mmol) in tetrahydrofuran (3 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 resulting residue was purified on silica gel, eluting with 0 to 100% ethyl acetate in hexane, to give the desired product. LCMS calculated for C16H18ClN2O2 (M+H)+: m/z=305.1; Found: 305.0.
