4-Nitroaniline → N-(4-nitrophenyl)-3-chloropropane-1-sulfonamide

Participants

Reaction Steps

A solution of 5.00 g (36.2 mmol) of 4-nitroaniline and 6.41 g (36.2 mmol) of 3-chloropropanesulfonyl chloride in 20 ml of pyridine is stirred overnight at room temperature. The reaction mixture is then poured onto ice. The precipitate which deposits in the process is filtered off with suction and dried, giving N-(4-nitrophenyl)-3-chloropropane-1-sulfonamide as a yellowish solid; ESI 279.
