2-(5-(Methoxymethoxy)-2-methylpyridin-4-yloxy)ethanol (900 mg, 4.22 mmol) was dissolved in ethyl acetate (10 mL), added 4N hydrochloric acid-ethyl acetate solution (10 mL), and the mixture was stirred at room temperature for 5 hours. After the reaction has terminated, under ice-cold conditions, a 4N aqueous solution of sodium hydroxide was used to adjust the reaction solution to pH=8. The reaction solution was concentrated in vacuo. The obtained residue was washed with chloroform/methanol, dried, and as a crude product, 4-(2-hydroxyethoxy)-6-methylpyridin-3-ol (1.2 g) was obtained as a white solid.
