Procedure
A mixture of 4.42 g of 7-(3-pyridyl)pyrazolo[1,5-a]pyrimidine-3-carbonitrile, 50 ml. of glacial acetic acid and 5 ml. of 30% hydrogen peroxide is heated on a steam bath for 2 hours. The mixture is cooled, filtered and the solid recrystallized from acetic acid to give 2.05 g. of the product of the example, m.p. 294°-295° C.
