Reaction Steps

A suspension of 2.50 g of methyl 7-mercapto-5-methyl-s-triazolo [1,5-a]pyrimidine-2-carboxylate (See Eur. Pat. Publ. 150,507) in 25 ml of 25 percent aqueous ammonia was stirred at room temperature for 6 hours. The mixture was filtered and the solid was dried at 50° in a vacuum. There was obtained 7-mercapto-5-methyl-s-triazolo[1,5-a]pyrimidine-2-carboxamide as a 1:1:1 adduct with water and ammonia.
