Renaissance of 4-(5-nitrofuran-2-yl)-5-arylamino substituted pyrimidines: microwave-assisted synthesis and antitubercular activity

The Buchwald-Hartwig cross-coupling of 5-bromo-4(furan-2-yl)pyrimidine with various anilines afforded the corresponding new 5-(arylamino)pyrimidines, the reaction being accelerated by microwave irradiation. Most of the obtained compounds proved to possess a high bacteriostatic in vitro effect against Mycobacterium tuberculosis H(37)Rv, Neisseria gonorrhoeae, and Staphylococcus aureus including Methicillin-resistant strain, which is stronger than that of the commercial drug Spectinomycin.
