Procedure

To stirred suspension of 3.35 g of 50% sodium hydride and 10.92 g of benzyl bromide in 75 ml of dimethylformamide was added a solution of 19 g of 1-(hexadecyloxy)-3-buten-2-ol in 75 ml of dimethylformamide. The mixture was stirred overnight, then water was added and the mixture was extracted with ether. The ether extract was dried over magnesium sulfate and activated charcoal and the solvent removed giving an oil. This oil was purified by HPLC [hexane: chloroform (8:1)] and the solvent removed giving 12 g of the desired compound as an oil.
