Simple Summary
Isatin, its 5-chloro and 5-bromo derivatives have beer) reacted with 4-(4-chloropheny1)-6-(4-methylphenyl)-2-aminopyrimidine to form Schiff bases and the N-Mannich bases of these compounds were syrlthesized by reacting thern with folmaldehyde and several secondary arnines. The cornpoullds were evaluated in vitro against Mycobacterium tuberculosis H37Rv at 6.25 μg/ml in BACTEC 12l3 tnediunl using the BACTEC 460 radiometric system. Among the cotnpounds tested 3-[4-(4-ch1orophenyl)-6-(4- methylphenyl) pyrimidin-2-yl]iminoisatin (Sl) showed prornising activity with 97% inhibition at a concentration of 6.25 μg/ml.
