Reaction Steps
On reacting 27 g of phenyl isothiocyanate and 15 g of acetylhydrazine in ethanol at room temperature, 1-acetyl-4-phenylthiosemicarbazide was formed. This 1-acetyl-4-phenylthiosemicarbazide was filtered off and heated under reflux in ethanol in the presence of sodium ethylate whereupon 3-mercapto-5-methyl-4-phenyl-1,2,4-triazole was formed.
