To a solution of 10 g of 5-(benzyloxy)-2-(hydroxymethyl)pyridin-4(1H)-one in 58 mL of pyridine, 4.6 mL of acetyl chloride was added under cooling with ice, and the mixture was stirred at 60 to 70° C. for 3 hours. The solvent was distilled off under reduced pressure, water was added thereto, and the mixture was stirred under cooling with ice. The solid was filtered off, chloroform was added thereto and the resultant was dried over anhydrous magnesium sulfate, the solvent was distilled off under reduced pressure. Thereto was added diethyl ether and the solid was filtered off to obtain 9.2 g of (5-(benzyloxy)-4-oxo-1,4-dihydropyridin-2-yl)methyl acetate as a light brown solid.
