Reaction Steps

4-(Diethoxymethyl)-1-methylpyridinium iodide (3.43 g, 10.6 mmol) was dissolved in water (70 mL). To this, a solution of potassium ferricyanide (38.4 g, 117 mmol) in water (85 mL) was added dropwise under a nitrogen atmosphere at 0° C. over 1 hour. To this, an aqueous solution (16 mL) of potassium hydroxide (9.40 g, 167 mmol) was added dropwise at the same temperature over 30 minutes. To this, toluene (100 mL) was added and the mixture was stirred at 40° C. for 30 minutes. Then, extraction with dichloromethane was performed, followed by drying over anhydrous sodium sulfate. The solvent was evaporated off under reduced pressure, and the residue was purified by silica gel column chromatography (ethyl acetate) to give 1-methyl-4-(diethoxymethyl)-2(1H)-pyridone (1.20 g, yield: 53%).
