- 中文摘要: Several pyrazolo(3,4-b)pyridine(3,4) and pyrazolo-(3,4-d)pyrimidine (5,13) derivatives were prepared using 5-amino-1-(5-ethyl-5H-1,2,4-triazino(5,6-b)-indol-3-yl)- 1H-pyrazole-4-carbonitrile (2). The pyridine derivatives 3 and 4 were obtained by reaction of 2 with malononitrile and ethyl cyanoacetate, respectively, while pyrimidine analogs 5-13 were synthesized either by a one-step or multi-step sequence.
