A practical, inexpensive, and rapid method for the stereoselective synthesis of pyrazolo[4,3‐ c ]pyridine derivatives via microwave‐assisted reactions of 3,5‐diarylidenepiperidin‐4‐ones with phenylhydrazine in ethylene glycol. This method has the advantages of good yield, operational simplicity, and simple purification procedure. J. Heterocyclic Chem., (2009).
