4-PHENYL-2H-pyrazol-3-ylamine 3 has been prepared by reaction of 2-phenyl-3-piperidine-1-yl-acrylonitrile(6) with hydrazine hydrate under microwave irradiation. Compound 3 reacted with acetylacetone and ethyl acetoacetate to yield pyrazolopyrimidine derivatives 7 and 8, respectively. Pyrazolopyrimidine derivative 11 can be formed by reaction of 3 with 2-ethoxymethylene-malononitrile. Compound 3 can be diazotised to yield the diazonium chloride and coupled with 6 to yield pyrazolotriazine derivative 25. Structures of the synthesized compounds were confirmed by their IR and NMR spectroscopic data.
