A mixture of 13.8 g of 3-acetoxy-2-(ethoxycarbonyl)methoxypyridine, 4.38 g of potassium carbonate and 60 ml of ethanol was stirred for over night at room temperature. The reaction solution was poured into a mixture of water, sodium chloride and hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with saturated saline, dried over anhydrous magnesium sulfate, and concentrated. The residue was subjected to silica gel column chromatography to obtain 10.45 g of 3-hydroxy-2-(ethoxycarbonyl)methoxypyridine.
