Participants

Reaction Steps

Thirty grams of 1-(p-aminophenyl)-1,2,3,4-tetrazole-5-thiol was dissolved in 300 ml of acetonitrile and 20 ml of pyridine, and 16 ml of methacrylic acid chloride was added dropwise to the resulting solution with agitation. After the addition of the methacrylic acid chloride, the mixture was agitated for 1 hour at room temperature. Thereafter, a 10% aqueous solution of sodium hydroxide was added and the mixture was agitated for a white. The mixture was rendered weakly acidic with dilute hydrochloric acid and the end compound was obtained as a white crystal in an amount of 29.4 g (yield, 72%).
