Procedure

A mixture of 2-dimethylamino-6-nitro-benzenesulfonamide (753 mg, 3.07 mmol), Pd (10%) on charcoal (100 mg) and methanol (25 ml) is hydrogenated at 25° C. for 2 h. Pd is removed by filtration, the solvent evaporated and the residue crystallized from TBME/cyclohexane to give 2-amino-6-dimethylamino-benzenesulfonamide as a colorless solid.
