1,2,3-triazole (2 g, 28.96 mmol) was dissolved in 1,4-dioxane (40 mL), and potassium carbonate (8 g, 57.92 mmol), potassium iodide (962 mg, 5.79 mmol) and 3-bromopropanol (3.3 mL, 43.43 mmol) were added thereto, followed by stirring at 100° C. for 3 hours. After the reaction was completed, the reactants were cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The resulting residue was purified by column chromatography to afford the title compound (2.5 g, 68%).
