Reaction Steps

To a solution of 2-(4-fluoro-phenyl)-4-oxo-3,4-dihydro-2H-pyridine-1-carboxylic acid (2-bromo-4-chloro-5-methylsulfanyl-phenyl)-amide (0.050 g, 0.106 mmol) in methanol (2 ml) and acetonitrile (2 ml) was added oxone (0.131 g, 0.213 mmol) and water (0.3 ml). The mixture was stirred at room temperature for two hours. Water was added and the mixture was extracted with EtOAc. The organic extract was washed with water and brine, dried over MgSO4, filtered and concentrated to dryness under reduced pressure. Purification of the residue by flash chromatography (EtOAc) gave 2-(4-fluoro-phenyl)-4-oxo-3,4-dihydro-2H-pyridine-1-carboxylic acid (2-bromo-4-chloro-5-methanesulfonyl-phenyl)-amide (0.009 g) as a white foam. MS (M+H) 502.
