To a solution of 5-(methoxymethoxy)-2-methylpyridin-4(1H)-one (1.28 g, 7.56 mmol) in N,N′-dimethylformamide (19 mL), potassium carbonate (2.10 g, 15.1 mmol) and 2-bromoethanol (804 μL, 11.3 mmol) were added sequentially, and the resultant mixture was stirred at 90° C. overnight. After completion of the reaction, the reaction solution was concentrated in vacuo. The obtained residue was dissolved in chloroform/methanol, solid substance was filtered, and the filtrate was concentrated in vacuo. The obtained residue was purified using column chromatography (hexane/acetone) and 2-(5-(methoxymethoxy)-2-methylpyridin-4-yloxy)ethanol was obtained as an orange oil (900 mg, yield 56%).
