Reaction Steps

N-Hexadecyl-3-nitro-4-chlorobenzenesulfonamide (170 grams) was dissolved in 640 ml of acetone. 79 grams of potassium carbonate, 6 ml of poly(ethylene glycol) and 71 grams of dimethylsulfate were added and the mixture was heated under reflux for a period of 5 hours. Acetone (240 ml) was added, 870 ml of water was added dropwise at 40° C. and crystals precipitated out on cooling the mixture to room temperature.
