2-(1,3-Oxazol-5-yl)pyridine (2.8 g, 19 mmol) and 3-chloroperbenzoic acid (77%, 13.6 g, 58 mmol) were dissolved in ethyl acetate, and the mixture was stirred at room temperature for 6 days. The solvent was evaporated, and the residue was subjected to a silica gel column chromatography. The fractions eluted with methanol-ethyl acetate (1:4, v/v) were collected and concentrated to give the titled compound (1.1 g, 34%).
