| Abstract: | A straightforward and highly efficient procedure has been described for the synthesis of 6-aryl-12H-pyrido[2',3':4,5]pyrimido [1,2-⍺][1,8]naphthyridin-12-ones 3 by the reaction of 3-aryl-2-chloro-1,8-naphthyridines 1 with 2-aminonicotinic acid 2 in glacial acetic acid under microwave irradiation. The products are obtained in very good yields and in a state of high purity. The structural assignments of compounds 3 were based on their elemental analyses and spectral (IR and ¹H NMR) data. |
