実験手順

A mixture of 2-fluoro-N-(2-oxo-1H-pyridin-4-yl)-4-(trifluoromethyl)-benzamide (13.6 g, 45.30 mmol), 4-fluoro-2-methyl-phenol (17.1 g, 135.9 mmol), Cs2CO3 (44.28 g, 135.9 mmol) and DMF (340.0 mL) was heated at 100° C. for 1.5 hours. The mixture was cooled to room temperature and was poured into water (500 mL). The mixture was stirred vigorously for 30 min before it was filtered. The solid was washed with water (250 mL) and was slurried with methyl tert-buthyl ether (200 mL). The mixture was filtered and the solid was slurried with hexanes (2×400 mL) and the filtrate was dried under vacuum to give 2-(4-fluoro-2-methyl-phenoxy)-N-(2-oxo-1H-pyridin-4-yl)-4-(trifluoromethyl)benzamide (9a) (13.1 g, 70%) as a solid. ESI-MS m/z calc. 406.09, found 407.5 (M+1)+; Retention time: 1.73 minutes (3 minutes run). 1H NMR (400 MHz, DMSO-d6) δ 11.28 (s, 1H), 10.63 (s, 1H), 7.84 (d, J=7.8 Hz, 1H), 7.60 (d, J=7.1 Hz, 1H), 7.31 (d, J=7.2 Hz, 1H), 7.26-7.20 (m, 1H), 7.14-7.06 (m, 2H), 7.00-6.95 (m, 1H), 6.75 (d, J=1.8 Hz, 1H), 6.38 (dd, J=7.2, 2.1 Hz, 1H), 2.16 (s, 3H) ppm.
