Reaction Steps

A mixture of 2-amino-5-mercapto-1,3,4-thiadiazole (39.9 g), potassium carbonate (41.4 g), α-chlorotoluene (38.0 g), and N,N-dimethylformamide (180 ml) is heated for 1.5 hours on a steam bath. The reaction mixture is drowned into water (1,000 ml) and the product collected by filtration and air dried. The crude product is recrystallized from ethanol and melts at 154°-156° C.
