Versuchsvorschrift

Cs2CO3 (651.6 mg, 2.0 mmol) was added to a solution of 2-fluoro-N-(2-oxo-1,2-dihydropyridin-4-yl)-5-(trifluoromethyl)benzamide (60.0 mg, 0.2 mmol) and 4-fluoro-3-methoxyphenol (228 μl, 2.0 mmol) in DMF (1 mL) and the reaction was stirred at 100° C. for 1 hour. 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-methoxyphenoxy)-N-(2-oxo-1,2-dihydropyridin-4-yl)-5-(trifluoromethyl)benzamide (30) (67.9 mg, 80%). ESI-MS m/z calc. 422.09. found 423.2 (M+1)+; Retention time: 1.56 minutes (3 minutes run).
