Procedure: To the above sulfamoyl chloride solution in acetonitrile was added dropwise with stirring a solution of 8.4 g (0.05 mole) of 3-phenoxy-1,2-propanediol (95% purity obtained from Aldrich Chem. Co., Inc.) and 20.2 g (0.2 mole) of triethylamine in 50 ml of acetonitrile at such a rate that the temperature did not exceed 12° C. over a 45 min period. The cooling bath was removed and the mixture was stirred for 2 hr and treated with 100 ml of ethyl acetate and 50 ml of water. The mixture was vigorously stirred for 5 min and the layers were separated. The organic layer was washed with 50 ml of water and 100 ml of salt brine, dried over sodium sulfate and concentrated to give a gum as residue. The gum was purified by column chromatography on 350 g of silica gel. Fractions eluted with 15% acetone in methylene chloride were combined and concentrated to give a clear gum as residue. The gum was triturated with petroleum ether (b.p. 30°-60° C.) to give crystalline solid. The solid was collected by filtration and recrystallized from benzene-acetonitrile to yield 4.2 g (26% yield) of white solid title compound, mp 116°-118° C.
