A series of 2-amino-4-(1-naphthyl)-6-arylpyrimidines have been synthesized and characterized by IR, NMR, MS, elemental analyses and evaluated for in vitro antibacterial and antifungal activities. Some of the compounds were found to be active against a limited panel of bacteria and fungi. In particular, compounds 4b and 4e were found to be the most effective analogs against the tested bacterial and fungal strains.
