Reaction Steps

Then, sodium benzoate (50.44 g, 0.35 mol) were added to a mixture of 4-bromomethyl-2,2-dimethyl-1,3-dioxolane (58.52 g, 0.3 mol) and N,N-dimethylformamide (500 ml) and the resulting mixture was stirred for 15 hours at 150° C. After cooling the salt was filtered and N,N-dimethylformamide was removed in vacuo and water was added to the residue and extracted with toluene. The extract was washed with saturated brine, dried over anhydrous sodium sulfate and condensed in vacuo to give 64.5 g of crude 4-benzoyloxymethyl-2,2-dimethyl-1,3-dioxolane (yield 91%).
