Procedure

A mixture of 3.2 g. 2-amino-1-nitro-4-(1,2,4-triazol-3-ylthio)benzene, 3.2 g. of iron powder, 1.6 g. ferrous sulfate in 240 ml. methanol and 60 ml. water is refluxed for 6 hours (with one additional portion of iron being added after 3 hours). The mixture is cooled, filtered and the filtrate stripped under vacuum to yield 1,2-diamino-4-(1,2,4-triazol-3-ylthio)benzene.
