実験手順

To a solution of the 4-(2-(methylthio)benzo[d]oxazol-6-yloxy)-N-methylpyridine-2-carboxamide (1.26 g, 4.0 mmol, 1.0 eq) in 40 mL of methylene chloride was added 3-chloroperoxybenzoic acid (70%, 989 mg, 4.4 mmol, 1.1 eq). The reaction mixture was stirred at room temperature for 5 hours and then was diluted with 200 mL of methylene chloride. The resulting mixture was washed with aqueous sodium bicarbonate and brine then dried over MgSO4, filtered, and evaporated under reduced pressure to give crude product, which was used to next step without further purification. MH+=332.
