실험 절차

A solution of 2.0 g. 2-mercaptoimidazole in 25 ml. dimethylformamide is treated with 0.85 g. of 57% sodium hydride (in oil suspension). 3.0 G. of 2-amino-4-chloro-1-nitrobenzene is added and the mixture heated overnight at 150°-155°C. The mixture is diluted with water, filtered and the crude product washed with chloroform, recrystallized from aqueous methanol to yield 2-amino-4-(imidazol-2-ylthio)-1-nitrobenzene.
