Versuchsvorschrift

To a prewashed suspension of about 10.8 g of sodium hydride in about 800 ml of dimethylformamide was added about 43.5 g of 4-tetradecylphenol. The reaction was then refluxed about 2 hours, cooled to room temperature and about 37.8 g of freshly prepared 2,2-dimethyl-4-[[(methylsulfonyl)oxy]methyl]-1,3-dioxolane was added. The reaction was then refluxed for about 24 hours, cooled, diluted with ether, washed with water and dried, giving about 58.7 g of the desired title compound, mp 52°-53° C.
