Versuchsvorschrift
By reacting 27 g of phenyl isothiocyanate and 15 g of acetylhydrazine in ethanol at room temperature, 1-acetyl-4-phenylthiosemicarbazide was formed, which was collected by filtration and refluxed in ethanol in the presence of sodium ethylate to provide 3-mercapto-5-methyl-4-phenyl-1,2,4-triazole.
