Reaction Steps

A solution of 2-fluoro-5-(trifluoromethoxy)benzoic acid (5.3 g, 23.47 mmol), HATU (8.92 g, 23.47 mmol), 2-methoxypyridin-4-amine (2.9 g, 23.47 mmol) and Et3N (13.09 mL, 93.88 mmol) in dichloromethane (47.4 mL) was stirred at room temperature overnight. The crude mixture was purified by column chromatography eluting with a gradient of ethyl acetate in hexanes (0-50%) to yield 2-fluoro-N-(2-methoxy-4-pyridyl)-5-(trifluoromethoxy)benzamide (5.03 g, 65%) as a white solid. ESI-MS m/z calc. 330.06. found 331.1 (M+1)+; Retention time: 1.48 minutes (3 minutes run). 1H NMR (400 MHz, DMSO-d6) δ 10.90 (s, 1H), 8.10 (m, 1H), 7.73 (dd, J=5.1, 3.2 Hz, 1H), 7.66 (m, 1H), 7.55 (t, J=9.2 Hz, 1H), 7.21 (dd, J=3.7, 1.8 Hz, 2H), 3.84 (s, 3H) ppm.
