1.2 G. 1-amino-2-nitro-4-methoxymethylthiobenzene is reduced in 80 ml. methanol and 20 ml. water at reflux with 2.4 g. iron powder and 0.6 g. ferrous sulfate. The mixture is filtered and concentrated. The residue is recrystallized from cyclohexane, yielding pure 1,2-diamino-4-methoxymethylthiobenzene.
