Reaction Steps

A mixture of 2.6 g. of 2-amino-4-(imidazol-2-ylthio)-1-nitrobenzene, 2.6 g. of iron powder and 1.3 g. ferrous sulfate in 200 ml. methanol and 50 ml. water is refluxed for 2 hours. An additional 2.6 g. of iron is added and refluxing continued for 2 hours. The mixture is filtered and the filtrate stripped to yield 1,2-diamino-4-(imidazol-2-ylthio)benzene.
