Procedure

To a solution of 1-hydroxy-N-[(1S,2S)-2-hydroxycyclohexyl]-4-{[6-(1H-pyrazol-1-yl)pyridine-3-yl]methyl}-2-naphthamide (Example 6, 0.120 g, 0.271 mmol) in 4 mL of DMF was added potassium carbonate (0.041 g, 0.30 mmol) and iodomethane (0.042 g, 0.30 mmol). After 24 hours, the reaction was diluted with ethyl acetate, washed with water, dried over sodium sulfate, filtered, and concentrated in vacuo. The residue was purified via silica gel chromatography, eluting with 0-10% methanol in dichloromethane to provide the title compound that gave a proton NMR spectra consistent with theory and a mass ion (ES+) of 457.4 for [M+H]+: 1H NMR (400 MHz, CDCl3) δ 8.50 (br s, 1H), 8.30 (br s, 1H), 8.22-8.11 (m, 2H), 8.03 (s, 1H), 7.92 (d, J=6.9 Hz, 1H), 7.84 (br s, 1H), 7.70 (br s, 1H), 7.57 (br s, 2H), 6.44 (br s, 1H), 4.44 (s, 2H), 4.03 (s, 3H), 3.98 (br s, 1H), 3.53 (br s, 1H), 2.36-2.14 (m, 3H), 1.79 (br s, 2H), 1.47-1.26 (m, 3H).
