Procedure

To a slurry of 1.04 g of lithium borohydride in tetrahydrofuran at ambient temperature is added 29 g of ethyl 3-(hexadecyloxy)-2-[(hexadecylthio)methyl]propanoate followed by heating at reflux for 18 hours. The mixture is poured into water containing a small amount of acid followed by extraction with ether to give after drying and evaporation, a residue which is columned on silica gel using 30:1 hexane:ethyl acetate. Fractions containing the product are evaporated to give 18.4 g of the desired product.
