[NH2:1][C:2]1[CH:7]=[CH:6][C:5]([S:8][CH2:9]COC)=[CH:4][C:3]=1[N+:13]([O-])=O.[CH3:16][OH:17]>[Fe].O>[NH2:1][C:2]1[CH:7]=[CH:6][C:5]([S:8][CH2:9][O:17][CH3:16])=[CH:4][C:3]=1[NH2:13]1.3 G. of 1-amino-2-nitro-4-methoxyethylthiobenzene 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 4 hours. The mixture is filtered, stripped under vacuum, and the residue recrystallized from cyclohexane. 1,2-Diamino-4-methoxymethylthiobenzene is thus obtained.
