Procedure

A mixture of 11.68 g of 3-(2-ethyl-4-tetradecylphenoxy)-1,2-propanediol, 14.95 g of trityl chloride and 40 ml pryridine was stirred for 72 hours, then diluted with chloroform, washed with two 100 ml portions of aqueous sodium bicarbonate, then water and dried. The solvents were evaporated under reduced pressure and the residue evaporated with toluene. This residue was then diluted with hexanes and the solid which formed collected giving 18 g of the desired compound.
