Procedure

A mixture of 7.7 g (34 mmole) of 7-mercapto-5-methoxycarbonyl-2-methyl-s-triazolo[1,5-a]pyrimidine and 70 ml of a 2N NaOH was stirred at room temperature for 2 hours and then ice-cooled. The pH of the mixture was adjusted to 2 with 6N HCl. The precipitates were collected by filtration and washed with water and then acetone, followed by drying, to obtain 7.08 g of the title compound (Yield: 99%).
