実験手順

3-Chloro-2,5-dimethylpyridine (1.10 g) was dissolved in dichloromethane (30 mL). m-Chloroperbenzoic acid (1.61 g) was added with stirring under ice-cooling, and the mixture was stirred at room temperature overnight. The reaction solution was washed with 1 N sodium hydroxide, and the organic layer dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain the title compound (1.21 g, 99%) as a solid.
