Procedure

A stirred mixture of 7-acetyl-5-chloroquinolin-8-yl trifluoromethanesulfonate (0.12 g, 0.34 mmol, from Example 47, Step 2), 1-cyclopropylpiperazine dihydrochloride (0.081 g, 0.41 mmol), palladium acetate (1.5 mg, 0.0068 mmol), (S)-(−)-2,2′-bis(diphenylphosphino)-1,1′-binaphthyl (6.3 mg, 0.010 mmol), and cesium carbonate (0.44 g, 1.4 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 and evaporated to dryness. The residue was purified on silica gel (eluting with 0 to 10% MeOH in dichloromethane) to give the desired product (61.1 mg, 55%). LCMS calculated for C18H21 ClN3O (M+H)+: m/z=330.1; Found: 330.1.
