Reaction Steps

To a solution of 2-fluoro-N-(2-oxo-1H-pyridin-4-yl)-4-(trifluoromethyl)benzamide (211.2 mg, 0.70 mmol) and 4-fluoro-2-(hydroxymethyl)phenol (100 mg, 0.70 mmol) in N-methyl pyrrolidinone (3 mL) was added cesium carbonate (687.8 mg, 2.1 mmol) and the mixture was heated at 100° C. for 2 hours. The reaction was cooled to 25° C., filtered and purified by reverse phase HPLC using a gradient of acetonitrile/water (10 to 99%) and HCl as a modifier to yield 2-[(5-fluoro-2-hydroxy-phenyl)methoxy]-N-(2-oxo-1H-pyridin-4-yl)-4-(trifluoromethyl)benzamide (159) (10.5 mg, 3%) as a yellow solid. 1H NMR (400 MHz, DMSO-d6) δ 11.52 (s, 1H), 10.49 (s, 1H), 10.04 (s, 1H), 7.84 (d, J=8.2 Hz, 1H), 7.78 (d, J=7.4 Hz, 1H), 7.33-7.23 (m, 2H), 7.05-6.91 (m, 2H), 6.91-6.79 (m, 2H), 6.61 (dd, J=7.4, 2.4 Hz, 1H), 4.96 (s, 2H) ppm. ESI-MS m/z calc. 422.09. found 423.3 (M+1)+; Retention time: 1.83 minutes (3 minutes).
