6 G of 2nitro-4-(3-chloropropylthio)aniline is treated in 120 ml. methanol and 120 ml. of water with 30 g. of sodium hydrosulfite (Na2S2O4) on the steam bath for about 5 minutes. The reaction mixture is concentrated under vacuum and extracted well with chloroform. Evaporation of the dried extract affords 1,2-diamino-4-(3-chloropropylthio)benzene.
