반응 단계
To a mixture of 4-hydroxymethyl-2,2-dimethyl-1,3-dioxolane (5.35 g) and pyridine (15.65 g) in dichloromethane (200 ml) was added acetic anhydride (20.56 g), and the mixture was stirred at ambient temperature for 12 hours. The mixture was poured into a mixture of water and ethyl acetate. The organic layer was separated, washed with saturated aqueous sodium hydrogen carbonate and brine successively, dried over magnesium sulfate, and evaporated in vacuo to give 4-acetoxymethyl-2,2-dimethyl-1,3-dioxolane (6.02 g).
