## Abstract magnified image A series of pyrazolo[3,4‐__b__]pyridines has been synthesized by __FriedlΓ€nder__ condensation of 5‐amino‐pyrazole‐4‐carbaldehyde **1** with active methylene compounds in basic medium. Pyrazolo[4β€²3β€²:5,6]pyrido‐[2,3‐__d__]pyrimidines have been synthesized from pyrazolo[3,
