実験手順
To a solution of 49 mg of (5-ethyl-4-methoxypyridin-2-yl)methanol in 1 mL of dichloromethane, 0.13 g of manganese dioxide was added. The mixture was stirred at room temperature for 1 hour 30 minutes, 0.13 g of manganese dioxide was then added thereto, and the mixture was stirred for 1 hour 30 minutes. Chloroform was added to the reaction mixture, the insoluble substance was filtered off, and the solvent was distilled off under reduced pressure to obtain 54 mg of 5-ethyl-4-methoxypyridine-2-carbaldehyde as a brown oily substance.
