反応手順
tert-Butyl 3-(3-methylpyridin-4-yl)benzoate (0.500 g, 1.86 mmol) was dissolved in a mixture of dichloromethane (0.800 mL) and 30% hydrogen peroxide (0.421 mL). Methyltrioxorhenium (VII) (2.3 mg, 0.92 mmol) was added and the reaction mixture was stirred vigorously for 5 hours. The layers were then separated and the organic layer was treated with sodium sulfite, and then dried over sodium sulfate. The crude product filtered, evaporated to dryness, and used without further purification. ESI-MS m/z calc. 285.1. found 286.1 (M+1)+. Retention time 1.22 minutes.
