実験手順

11.4 g of 5-ethyl-5-methacryloyloxymethyl-2-oxo-1,3-dioxane, 3.2 g of methanol and 0.285 g of p-toluenesulfonic acid were dissolved in 100 g of 1,2-dichloroethane. The solution was stirred for 2 hours at 40° C. and evaporated in vacuo to remove the solvent. After removing white precipitates by filtration, the residue was further concentrated whereupon the title compound was recovered as a colorless oil.
