Sodium hydride (50% in oil) (1.74 g, 36.3 mmoles) was washed with n-hexane and dried in a nitrogen gas stream. After addition of 80 ml of dry DMSO, the mixture was heated on a water bath at 70° C. for 30 minutes. When the mixture became homogeneous, 6.9 g (36.3 mmoles) of 2-methylglycerol tetrahydropyranyl ether was added dropwise and, after 15 minutes, 4.62 g (18.2 mmoles) of 1,2-epoxyheptadecane was added dropwise. The mixture was stirred at 70° C. for an hour, poured into 100 ml of broken ice and extracted with 300 ml of n-hexane-ethyl acetate (1:1). The extract was washed with water, dried and concentrated and the residue was purified by silica gel column chromatography to give 4.37 g (53.9%) of the desired compound as a colorless oil.
