Reaction Steps

In 200 ml of methanol was suspended 19.1 g of 3-mercapto-5-methyl-4-phenyl-1,2,4-triazole and then 20 g of a 28% sodium methylate solution to the suspension. After 10 minutes, 15 g of methyl iodide was added dropwise to the mixture. After performing the reaction for 10 minutes, methanol was distilled off and the product was extracted with ethyl acetate to provide 5-methyl-3-methylthio-4-phenyl-1,2,4-triazole.
