Reaction Steps

A solution of 0.5 g of (S)-2-O-benzyl-1-O-octadecyl glycerine in 25 ml of dichloromethane is treated with 0.3 ml of pyridine and cooled to 0° C. The solution is treated with 0.2 ml of 2-bromoethyl chloroformate, stirred at room temperature, treated with 10 ml of water and acidified to pH 3 with 1N hydrochloric acid. The organic phase is washed with water, dried and evaporated. The residue is chromatographed on silica gel while eluting with ether/n-hexane (1:1). There is obtained (R)-2-O-benzyl-1-[(2-bromoethoxy)carbonyl]-3-O-octadecylglycerine in the form of an oil.
