Procedure

2-Fluoro-N-(2-oxo-1H-pyridin-4-yl)-4-(trifluoromethyl)benzamide (625.3 mg, 2.08 mmol), potassium carbonate (287.9 mg, 2.08 mmol) and 4-fluoro-2-(hydroxymethyl)phenol (296 mg, 2.08 mmol) were added to 1-methylpyrrolidin-2-one (3.0 mL) and the reaction was stirred at 80° C. for 10 minutes. The reaction was filtered and the compound was purified by reverse phase preparative chromatography utilizing a gradient of 10-99% acetonitrile in water containing HCl as a modifier to yield 2-[4-fluoro-2-(hydroxymethyl)phenoxy]-N-(2-oxo-1H-pyridin-4-yl)-4-(trifluoromethyl)benzamide (157) (10.3 mg, 1%) as a white solid. 1H NMR (400 MHz, DMSO-d6) δ 11.44 (s, 1H), 10.66 (s, 1H), 7.86 (d, J=7.9 Hz, 1H), 7.61 (d, J=8.0 Hz, 1H), 7.41-7.27 (m, 2H), 7.24-7.12 (m, 1H), 7.12-7.07 (m, 1H), 7.04 (s, 1H), 6.80 (d, J=2.1 Hz, 1H), 6.43 (dd, J=7.3, 2.2 Hz, 1H), 4.47 (s, 2H) ppm. ESI-MS m/z calc. 422.09. found 423.2 (M+1)+; Retention time: 1.32 minutes (3 minutes run).
