Participants

Reaction Steps

A mixture of 3.5 g. 2-amino-4-chloro-1-nitrobenzene, 5.5 g. of potassium carbonate, 4.0 g. of 3-mercapto-1,2,4-triazole in 30 ml. dimethylformamide is heated under nitrogen for 4 hours at 130°-140°C. The mixture is cooled, diluted with water and the pH adjusted to about 6. The crude product is filtered off and recrystallized from methanol, yielding 2-amino-1-nitro-4-(1,2,4-triazol-3-ylthio)benzene.
