Water → N-[4-(2-Formylhydrazinyl)phenyl]-3-nitrobenzene-1-sulfonamide

Participants

Reaction Steps

15.1 g of 2-(4-aminophenyl)-1-formylhydrazine and 14 ml of triethylamine were dispersed in 50 ml of acetonitrile. To the dispersion, a solution containing 50 ml of acetonitrile and 22.1 g of 3-nitrobenzenesulfonyl chloride was added dropwise while stirring at room temperature. After heating at 60° C. for 2 hours, the reaction mixture was cooled and then poured into water. The resulting crystals were collected by filtration. 15 g of the object compound was obtained.
