Procedure

10% Palladium-carbon (3.19 g) was added to thus obtained 4-benzyloxymethyl-2,2-dimethyl-1,3-dioxolane (9.185 g, 41.32 mmol) in ethanol (250 ml) and the mixture was stirred for 3 hours at 25° C. under an atmosphere of hydrogen. After the reaction was over, palladium-carbon was filtered off and the solvent was condensed in vacuo. The crude product was distilled to give 4.70 g of 2,2-dimethyl-1,3-dioxolane-4-methanol (yield 86%, b.p. 72° C. at 8 mmHg).
