A simple and highly efficient procedure has been described for the synthesis of 9-aryl-6-(2-fluorophenyl)-1,2,4-triazolo[4,3-a][ 1,8]naphthyridines 8 by oxidation of the corresponding aryl aldehyde 3-(2-fluorophenyl)-1,8-naphthyridin-2-ylhydrazones 7 with chloramines-1 in ethanol under microwave irradiation The products are obtained in good yields and in state of high purity. The structures of the compounds 3-8 have been established on the basis of (IR, (II)-I-t NMR and MS) and analytical data
