Abstract
5-Chloroethylpyrazolo[3,4-b]pyridines were synthesized by condensation of 5-aminopyrazoles with α-acetyl γ-butyrolactone followed by cyclization treating with phosphorous oxychloride. 5-Chloroethyl-pyrazolo[3,4-b]pyridines, thus obtained, were then converted to the corresponded tricyclic pyrazolo[3,4-b]-pyrrolo[2,3-d]pyridines by treating with some primary amines.
