실험 절차

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