In 100 ml of dry dimethylformamide, 17.67 g of 3-hexadecyloxybutane-1,2-diol was treated with 2.36 g of 60% sodium hydride under chilling with ice. To the chilled mixture was added 6.77 g of benzyl chloride, and the resulting mixture was stirred at room temperature for 16 hours. The reaction mixture was recovered in a conventional manner and purified by silica gel column chromatography to give 4.33 g of 1-benzyloxy-3-hexadecyloxy-2-butanol.
