Reaction Steps
3-Hydroxy-4-(tetrahydro-2-pyranyloxy)-butyne (8.0 g, 0.047 mole) was mixed with acetic anhydride (10 g, 0.098 mole) and pyridine (8 g, 0.098 mole). The solution was stirred at room temperature for 1 hour and then extracted with ethyl acetate. The extract was sequentially washed with 10% hydrochloric acid (10 ml×5), saturated sodium bicarbonate aqueous solution (10 ml×5) and water (50 ml×3). The extract was dried over anhydrous magnesium sulfate, concentrated and separated by silica gel chromatography, eluted with n-hexane/ethyl acetate (5:1) to give colorless oil (9.0 g, 90%).
