Reaction Steps

A mixture of the methiodide of 5-chloro-N-methyl-N-phenyl-1,3-benzodithiol-2-iminium iodide (1.9 g), sodium carbonate (121 mg), N-aminorhodanine (338 mg) and dimethylformamide (20 ml) is heated at 50° C for 3 hours. The mixture is poured into water and the precipitate which forms is filtered and washed with water. The product is recrystallized from dimethylformamide to yield 600 mg of the title compound, melting point 312°-314° C.
