Reaction Steps

Cs2CO3 (146.6 mg, 0.45 mmol) was added to a solution of 2,5-difluoro-N-(2-oxo-1,2-dihydropyridin-4-yl)benzamide (37.5 mg, 0.15 mmol) and 4-trifluoro methoxyphenol (80.1 mg, 0.45 mmol) in DMF (0.9 mL) and the reaction was stirred at 100° C. for 8 hours. The reaction was filtered and purified by reverse phase HPLC using a gradient of acetonitrile in water (10-99%) and HCl as a modifier to yield 5-fluoro-N-(2-oxo-1,2-dihydropyridin-4-yl)-2-(4-(trifluoromethoxy)phenoxy)benzamide (101) (1.9 mg, 3%). ESI-MS m/z calc. 408.07. found 409.3 (M+1)+; Retention time: 1.68 minutes (3 minutes run).
