STUDIES IN THE FIELD OF NITROGEN HETEROCYCLIC COMPOUNDS. PART VIII. SYNTHESES AND STRUCTURES OF SOME NOVEL PYRAZOLOPYRIMIDINE DERIVATIVES

Cyclocondensation of ethyl β- and γ-pyridoylacetates (1, 2) with various substituted aminopyrazoles (3-6) was investigated.In the case of the reaction of 1, 2 with 3-5, using different experimental conditions, the corresponding pyrazolopyrimidines
