Some new fluorine-substituted 3,5-disubstituted amino-1,2,4-triazines have been obtained from aryl-amination of 2,2,2-trifluoro-N-[2-(5-hydroxy-3-thioxo-2,3-dihydro-1,2,4-triazin-6-yl)-4-nitrophenyl] acetamide followed by ammonolysis to produce N-(2-(5-amino-3-(arylamino)-1,2,4-triazin-6-yl)-4-nitrophenyl)-2,2,2-trifluoroacetamides which reacted with N-phenylthiourea. The structures of products were deduced from their elemental analysis and spectral measurements. The new lamotrigine analogs were evaluated in vitro as antibacterial. Interestingly, some compounds showed interesting activity against the Bacillus subtilis, Streptococcus faecalis, Micrococcus luteus, and Staphylococcus aureus bacteria.
