Procedure

A 1.0 g portion of 4,5,6,7-tetrahydro-2-methylpyrazolo[1,5-a]pyrimidine-3-carbonitrile was dissolved with stirring in 5.0 ml of concentrated sulfuric acid. The mixture was stirred for 6 hours at room temperature then poured onto ice. This mixture was made basic with concentrated ammonium hydroxide and then was filtered to give the product of the example as a colorless solid, mp 234°-236° C.
