Versuchsvorschrift

To a solution of the above N,N-dimethyl-3-nitro-benzenesulfonamide (20.4 mmol, 4.7 g) in ethanol (50 mL) was added SnCl2 (105 mmol, 19.9 g) and the mixture was refluxed for 1 hour. Upon cooling, the solvent was removed in vacuo. Ethyl acetate (200 mL) and NaHCO3 (sat, 100 mL) were added to the residue followed by another 200 mL ethyl acetate and 500 mL water. The phases were separated and the organic phase was washed twice with water. The organic phase was filtered, washed with water (2×100 mL) dried over MgSO4 and evaporated to leave the title compound.
