Reaction Steps

To 4-chlorobenzo[d]thiazol-2-amine (1.12 g, 6.07 mmol) in acetonitrile (30 mL) was added 1,1′-thiocarbonyldiimidazole (1.405 g, 7.89 mmol). The reaction mixture was stirred at 50° C. for 18 hours. The reaction was cooled to room temperature and the precipitate was filtered and washed with acetonitrile (2×50 mL). The yellow powder was dried in a vacuum oven (40° C.) for 1 hour to yield N-(4-chlorobenzo[d]thiazol-2-yl)-1H-imidazole-1-carbothioamide (0.33 g, 1.12 mmol, 18.5% yield) and then used in the next step without any further purification or characterization.
