Versuchsvorschrift

Diethylamine (2.4 g) was dissolved in pyridine (15 ml) and 3-nitrobenzenesulfonyl chloride (6.7 g) was added, followed by stirring at 50° C for 2 hours. The residue obtained by an evaporation of pyridine under a reduced pressure was dissolved in methylene chloride (150 ml), washed with water, 1 N hydrochloric acid, water, and saturated aqueous sodium chloride, and dried over anhydrous sodium sulfate. Evaporation of the solvent under a reduced pressure gave N,N-diethyl-3-(nitro)benzenesulfonamide (4.0 g).
