An unexpected multicomponent reaction of cyanothioacetamide with aromatic aldehydes and aminopyrazole under MWI was found and reported. It turned out to be an efficient and simple procedure for the preparation of pyrazolo[3,4-b] pyridine derivatives. The structure of the product was characterized by IR,MS, 1Hand 13CNMR, COSY and NOESY spectroscopy, X-ray crystallographic analysis, and by comparison with the authentic sample prepared with the known procedure.
