2 G. of 1-amino-2-nitro-4-(prop-2-en-1-ylsulfinyl)-benzene is treated for four hours in a refluxing mixture of 160 ml. methanol and 40 ml. water with 4 g. iron powder (added in two portions) and 1 g. ferrous sulfate. The mixture is filtered, and the filtrate concentrated. The residue is dissolved in chloroform and washed with water, then the solvent evaporated affording 1,2-diamino-4-(prop-2-en-1-ylsulfinyl)benzene.
