Procedure

2,2-Dimethyl-4-hydroxymethyl-1,3-dioxolane (26 g, 0.2 mol) is added to 38 g of p-toluenesulfonyl chloride (0.2 mol) in 200 mL of pyridine and allowed to stand at 0° C. for 24 h. Water was added, and the mixture extracted with ethyl acetate. The ethyl acetate extract was washed with water and brine, dried over Na2SO4, and evaporated to yield 2,2-dimethyl-4-tosyloxymethyl-1,3-dioxolane.
