反应详情

Dichloromethane (100 ml) was mixed with 44 grams of 5-nitro-2-chlorobenzenesulfonyl chloride and a dichloromethane solution which contained 48.4 grams of methyloctadecylamine and 36.1 ml of triethylamine was added dropwise to the mixture. After the reaction had been completed the reaction solvent was removed by distillation under reduced pressure, 300 ml of methanol was added and a solution was formed by heating. Crystals precipitated out on cooling the solution slowly and these were recovered by filtration and dried.
