摘要：

Several pyrazolo[3,4‐b]pyridine (3,4) and pyrazolo‐[3,4‐d]pyrimidine 5‐13 derivatives were prepared using 5‐amino‐l‐(5‐ethyl‐5H‐1,2,4‐triazino[5,6‐b]‐indol‐3‐yl)‐lH‐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 cither by a one‐step or multi‐step sequence.
