Abstract: Several new pyrazolo[3,4-d]pyrimidines and pyrazolo[3,4-b]pyridine derivatives were prepared by
condensation of 5-amino-1-(5,6-diphenyl-1,2,4-triazin-3-yl)-1H-pyrazole-4-carbonitrile with succinic
anhydride, acetic anhydride, γ-chlorobutyl chloride, succinyl chloride, formic acid—formamide mixture,
formamide, and active methylene reagents such as malononitrile, ethyl cyanoacetate, and ethyl
acetoacetate under different reaction conditions.
