Reaction Steps

5-(1-methylethoxy)-2-methylpyridine (227 mg, 0.661 mmol) was dissolved in dichloromethane (7.5 mL), added 3-chloroperoxybenzoic acid (408 mg, 0.733 mmol) under ice-cold conditions, and the mixture was stirred at 0° C. for 45 minutes. The reaction solution was added ethyl acetate, saturated aqueous solution of sodium metabisulfite, and an aqueous solution of sodium hydrogen carbonate, and extracted with ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, and concentrated in vacuo. The obtained residue was purified by silica-gel column chromatography (ethyl acetate), and 5-(1-methylethoxy)-2-methylpyridine 1-oxide (240 mg (yield 6%)) was obtained as a colorless oil.
