An efficient and convenient method for the synthesis of 3-aryl- 4-formyl-1-[3-(4-fluorophenyl)-1,8-naphthyridin-2-yl]-pyrazoles 4 from acetophenone 3-(4-fluorophenyl)-1,8-naphthyridin-2- ylhydrazones 3 is achieved using POCl3-DMF over silica gel under microwave irradiation. The structural assignments of compounds 3 and 4 are based on their elemental analyses and spectral (IR, 1H NMR and MS) data. The compounds 4 have been screened for their antibacterial activity.

Alumina-supported iodobenzene diacetate [PhI(OAc)2-Al 2O3] is a highly efficient reagent for the oxidative cyclization of N-arylidene-N′-[3-(4-fluorophenyl)-[1,8]naphthyridin-2-yl]- hy-drazines 7 to 1-aryl-4-[4-fluoro phenyl]-1,2,4-triazolo[4,3-a][1,8] naphthyridines 8 in solvent-free conditions under microwave irradiation. The products are obtained in good yields and excellent purities. The structural assignments of compounds 3-8 were based on their spectral (IR, 1H NMR and MS) and analytical data.
