Reaction Steps

2-fluoro-N-(2-methoxy-4-pyridyl)-4-(1,1,2,2,2-pentafluoroethyl)benzamide (200 mg, 0.55 mmol) in HBr in acetic acid (1.3 mL of 33% w/v, 5.49 mmol) was stirred at 100° C. for 2 hours, at this time 1 ml of HBr in acetic acid (33% w/v) was added and the mixture was stirred at 100° C. for 4 hours, then cooled to room temperature. The reaction mixture was diluted with water and a precipitate formed. The precipitate was filtered off, washed with water (2×), cold methyl-tert-butyl ether and dried under vacuum to give 2-fluoro-N-(2-oxo-1H-pyridin-4-yl)-4-(1,1,2,2,2-pentafluoroethyl)benzamide (138 mg, 72%) as a light grey solid. ESI-MS m/z calc. 350.05, found 351.3 (M+1)+; Retention time: 1.3 minutes (3 minutes run).
