Description
Summary:The Buchwald-Hartwig amination reaction between 2-chloro-3-aryl-1,8-naphthyridines and 2-(4aminophenyl)-1H- benzo[de]isoquinoline-1,3(2H)-dione in the presence of the catalytic system Pd[([PPh.sub.3]).sub.4] and the base KO-t-Bu in toluene was studied. The reaction was initiated by microwave irradiation. Highly efficient synthesis has been developed for 2-{4-[(3-aryl-1,8-naphthyridin-2-yl)amino]phenyl}-1H-benzo[de]isoquinoline-1,3(2H)- diones. Structures of the synthesized compounds were evaluated by IR, [sup.1]H and [sup.13]C NMR spectroscopy. All products were tested for antimicrobial activity against Escheria coli, Bacillus subtilis, Klebsiella pneumoniae, and Staphylococcus aureus.
