Abstract

With of reaction of 5-amino-pyrazole-4-carbonitrile derivative and using from supported Preyssler heteropolyacid catalyst in a series from reactions prepared a several new pyrazolo[3,4-d]pyrimidine, pyrazolo[3,4-e][1,4]diazepine, pyrazolo[3,4- d][1,2,3]triazine and pyrolo[4,3-e][1,2,4]triazolo[1,5-c]pyrimidine derivatives.
