A suspension of sodium hydrogensulfide hydrate (3.88 g; 49 mmol) in Methanol (200 ml) was added to a solution of 3,5-dinitro-benzenesulfonamide (6 g; 24.27 mmol) in Methanol (500 ml). The reaction mixture was refluxed for 3 h then cooled to room temperature, filtered and concentrated in vacuo. The crude was washed with water, filtered and dried in vacuo. 3.2 g (15 mmol; 61% yield) of orange powder were obtained.
