Procedure

Cs2CO3 (651.6 mg, 2 mmol) was added to a solution of 2-fluoro-N-(2-oxo-1,2-dihydropyridin-4-yl)-5-(trifluoromethoxy)benzamide (63.2 mg, 0.2 mmol) and 4-fluoro-3-methylphenol (252.3 mg, 2 mmol) in DMF (1 mL) and the reaction was stirred at 100° C. for 1 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 2-(4-fluoro-2-methylphenoxy)-N-(2-oxo-1,2-dihydropyridin-4-yl)-5-(trifluoromethoxy)benzamide (40) (36.3 mg, 43%). ESI-MS m/z calc. 422.09. found 423.9 (M+1)+; Retention time: 1.64 minutes (3 minutes run).
