To 7 ml of a dioxane solution containing 1.4 g of N-(5-chloroacetylamino-4-nitro-2-phenoxyphenyl)methanesulfonamide was added 0.77 g of n-butylamine at room temperature, followed by stirring for an hour. Water was added to the reaction solution, the precipitate was collected by filtration and recrystallized from ethanol to give 1.1 g of N-[5-(n-butylaminoacetylamino)4-nitro-2-phenoxyphenyl]methanesulfonamide as yellow needles.
