Procedure

To a solution of 4-{[4-(4-chloropyridin-2-yl)-4-fluoropiperidin-1-yl]methyl}-8-fluoro-N-[(1S,2S)-2-hydroxycyclohexyl]quinoline-2-carboxamide (Example C) (0.022 g, 0.043 mmol) in THF (3 mL) under an atmosphere of nitrogen was added dimethyl zinc (2.0 M in THF, 0.043 mL, 0.085 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.0011 mg, 0.00090 mmol). The reaction was heated to 90° C., cooled to RT, and retreated with additional dimethyl zinc (2.0 M in THF, 0.043 mL, 0.085 mmol) and tetrakis(triphenylphosphine)palladium(0) (0.0011 mg, 0.00090 mmol). The reaction was heated to 100° C. for 5 h, then at 50° C. for an additional 16 h. The mixture was cooled to RT, diluted with ethyl acetate, and washed with saturated aqueous sodium bicarbonate and brine. The organic solution was dried over sodium sulfate, filtered, and concentrated in vacuo. The resultant residue was purified via silica gel chromatography eluting with 0-5% MeOH in dichloromethane to provide the title compound (Example D) as a white solid that gave a proton NMR spectra consistent with theory and a mass ion (ES+) of 495.1 for M+H+. 1H NMR (400 MHz, CDCl3) δ 8.39-8.36 (m, 2H), 8.30-8.20 (m, 2H), 7.69-7.38 (m, 3H), 7.00 (br s, 1H), 4.03 (s, 2H), 3.89 (br s, 1H), 3.59-3.49 (m, 1H), 3.48-3.14 (m, 1H), 2.85-2.81 (m, 2H), 2.61-2.57 (m, 2H), 2.44-2.37 (m, 2H), 2.37 (s, 3H), 2.18-2.13 (m, 2H), 1.87-1.79 (m, 4H), 1.50-1.14 (m, 4H).
