Procedure

A mixture of 33.06 g of 7-hydroxy-5-hydroxymethyl-2-methyl-s-triazolo[1,5-a]pyrimidine, 500 ml of DMF, 86 ml of anhydrous acetic acid and 1.5 g of p-toluenesulfonic acid was stirred in a bath at 50 ° C. for 6 hours. To an oily isopropanol to dissolve therein, and the solution was dropwise in 4 liters of ether. Precipitates were collected by filtration and dried to obtain 38.08 g of the compound.
