Versuchsvorschrift

3-Nitrobenzenesulfonyl chloride (22.8 mmol, 5.05 g) was dissolved in dry THF (50 mL). Dimethylamine in THF (2M, 34 mL) was added and the mixture was refluxed for 2 hours. Upon cooling, the mixture was filtered and the filtrate was evaporated in vacuo. The residue was dissolved in ethyl acetate (250 mL), washed with water (3×50 mL) and dried over MgSO4. Evaporation of the solvent afforded the title compound.
