Abstract: Microwave irradiation of acetophenone 3-(2-chlompheny l)-1,8-naphthyridin-2-y lhydrazones 2 on silica gel supported POCl3- DMF (Vilsmeier-Haack reagent) under environmentally friendly solvent-free condition provides a fast, efficient and simple method for the synthesis of 3-aryl-4-formyl-1-[3-(2-chlorophenyl)-1 ,8-naphthyridin-2-yl]pyrazoles 3 in good yields.
