Procedure

To a cooled solution of 0.0645 ml (0.75 mM) of oxalyl chloride in 50 ml of dichloromethane at -78° C., is added 0.106 ml (1.5 mM) of dimethylsulfoxide dropwise and the mixture is stirred for another 5 minutes. To this mixture is added a solution of 285 mg (0.5 mM) of 1-(3-chloropropylsulfonylamino)-2-(2-hydroxypropan-1-yl)-3-octadecylcarbamoyloxypropane m10 in 2 ml of dichloromethane at -70° C. with vigorous stirring. The mixture is allowed to react at -70° C. for 15 minutes and 0.836 ml (6 mM) of triethylamine is added. After allowing the temperature of the reaction mixture to rise to room temperature, the product is isolated with dichloromethane extraction. The dichloromethane layer is washed with 2N aqueous hydrochloric acid, water and saturated aqueous sodium bicarbonate, dried over anhydrous magnesium sulfate and evaporated to obtain crude product of the titled compound IIIm1.
