1.3 G. of 1-amino-2-nitro-4-methoxymethylthiobenzene is treated in 80 ml. methanol and 20 ml. water at reflux under nitrogen, with 0.7 g. ferrous sulfate and 2.8 g. iron (added in two portions) for four hours. The mixture is filtered, stripped under vacuum, and the residue recrystallized from cyclohexane. 1,2-Diamino-4-methoxymethylthiobenzene is thus obtained.
