Procedure: A solution of 80 g of (hexadecyloxy) acetic acid in 350 ml of tetrahydrofuran was stirred at 0° C. while 798.71 ml of 1M borane in tetrahydrofuran was added dropwise over one hour. When addition was complete the mixture was stirred 2 hours than 50 ml of acetone was added followed by 60 ml of water dropwise. The tetrahydrofuran was allowed to evaporate overnight, then the residue was mixed with water and chloroform and heated to dissolve the solid. The organic layer was separated, dried and the solvent removed. The residue was recrystallized from cold methanol, giving 70.6 g of the desired compound as a white solid, mp 42°-44° C. was added dropwise over one hour When addition was added to evaporate overnight the residue was mixed with water and chloroform heated to dissolve the solid The organic layer was separated dried the solvent removed The residue was recrystallized from cold methanol

Procedure: A solution of 49.4 g of oxalyl chloride in 900 ml of methylene chloride was cooled to -60° C. and a solution of 60.82 g of dimethyl sulfoxide in 175 ml of methylene chloride was added dropwise over 1/2 hour so that the temperature did not exceed -50° C. The solution was then warmed to -20° C. and maintained at -20° C. in a dry ice-carbon tetrachloride bath as a solution of 44.6 g of 2-(hexadecyloxy) ethanol in 350 ml of methylene chloride was added over 20 minutes. The mixture was stirred at -20° C. for 20 minutes, 98.2 g of triethylamine was added and the mixture was allowed to warm to room temperature. Water was added, then the organic layer was separated, washed with dilute hydrochloric acid then dilute aqueous sodium bicarbonate until neutral, dried over sodium sulfate and activated charcoal and filtered through silica gel. The solvent was removed at a temperature not exceeding 30° C. The residue was dissolved in petroleum ether, washed with dilute aqueous sodium bicarbonate, dried over sodium sulfate and filtered through magnesium silicate. The filtrate was stored as a solution in a freezer. Immediately prior to use as the starting material in Example 4, the solvent was removed from the filtrate, giving 32 g of the desired compound as a yellow solid. did not exceed -50° C was added over 20 minutes to warm to room temperature the organic layer was separated washed with dilute hydrochloric acid dilute aqueous sodium bicarbonate until neutral, dried over sodium sulfate and activated charcoal filtered through silica gel The solvent was removed at a temperature not exceeding 30° C The residue was dissolved in petroleum ether washed with dilute aqueous sodium bicarbonate dried over sodium sulfate filtered through magnesium silicate the solvent was removed from the filtrate
