To a solution of 1.02 g (2 mM) of 3-benzyloxy-2-methoxy-1-octadcylcarbamoylthiopropane VI a6 in 80 ml of acetonitrile is added 0.4 ml (2.81 mM) of trimethylsilyl iodide with ice-cooling and the mixture is allowed to stand at room temperature for 15 hours. To the reaction mixture is added 50 ml of 10% aqueous solution of sodium thiosulfate and the product is isolated with dichloromethane extraction. The dichloromethane layer is washed with water, dried, and evaporated. The residue is purified by column chromatography on silica gel using a n-hexane-ethyl acetate (2:1) mixture as an eluent to give 480 mg (1.15 mM) of the titled compound, 3-octadecylcarbamoylthio-2-methoxypropylalcohol V a6 as a solid in 57% yield.
