Reaction Steps

A stirred mixture of 7-acetyl-5-chloroquinolin-8-yl trifluoromethanesulfonate (0.12 g, 0.34 mmol, from Example 47, Step 2), 4-piperidinemethanol (0.047 g, 0.41 mmol), palladium acetate (1.5 mg, 0068 mmol), (S)-(−)-2,2′-bs(diphenylphosphino)-1,1′-binaphthyl (6.3 mg, 0.010 mmol), and cesium carbonate (0.31 g, 0.95 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 MgSO4, evaporated to dryness. The residue was purified on silica gel (eluting with 0 to 5% MeOH in dichloromethane) to give the desired product (30 mg, 28%). LCMS calculated for C17H20ClN2O2 (M+H)+: m/z=319.1; Found: 319.1.
