Hydrochloric Acid → HCID 10946692, compound

Participants

Reaction Steps

In a reaction flask with a thermometer and a stirrer, 25 g of p-nitrobenzenesulfonamide, 18 g of benzoylchloride, 1 g of copper powder, and 100 g of toluene were charged and refluxed until evolution of hydrogen chloride gas was completely ended. The reaction mixture was then cooled to room temperature to precipitate a crystal, which was filtered. The crystal was dissolved in an aqueous sodium carbonate solution and filtered. The filtrate was neutralized with hydrochloric acid to precipitate a crystal. The crystal was filtered to obtain 30.6 g of N-(4-nitrobenzenesulfonyl)benzamide.
