STUDIES ON CONDENSED PYRAZOLES: SYNTHESIS OF NEW METHYL AND AMINO PYRAZOLOPYRIMIDINES AND OF PYRAZOLOTRIAZINES

A variety of 3-arylazo 5-amino- and 7-aminopyrazolo-pyrimidines were obtained via reacting Ia-Id with cinnamonitriles.The structure of products was confirmed via 1H NMR.Both 5-amino- and 7-amino-3-arylazo pyrazolopyrimidines reacted, with protons in acetic acid-sulphuric acid mixture to yield the corresponding 3-unsubstituted acetylaminopyrazolopyrimidines.Diazotized Ia and Ib coupled with a variety of active methylene reagents to yield pyrazolotriazines.
