To a solution of 2-(4-chlorophenyl)-4-chlorosulfonylimidazole (1.3 g 0.005 m) in dioxane (15 ml) was added ethanolamine (0.61 g 0.01 ml). After 15 minutes the dioxane was removed under reduced pressure (20 mm) to yield a gum. The gum was slurried with water to yield a solid. The solid was filtered and recrystallized from acetonitrile to give 400 mg of 2-(4-chlorophenyl)-4-(2-hydroxyethylsulfamoyl)imidazole melting at 210°-212°. (20% yield). What is claimed is:
