In the present research, a series of Formazans derivatives 7a-j have been prepared by
the condensation of Schiff bases (4,5) and diazonium salt of substituted aromatic amines
Heterocycl, 6a-e. The intermediate Schiff bases (4,5), was itself synthesized by condensation of2-
amino benzothiazole (1), with 4-nitro and dimethylamino benzaldehyde, (2,3). All the reaction
were routinely monitored and purity was determind on thin layer chromatography using coated
aluminum plates and spots were visualized by exposing the dry plates in iodine vapours.The
structures of the compounds have been confirmed by , Mass spectroscopy 1H NMR, U.V, IR
spectral data and melting points. The antibacterial activity of the compounds has also been
screened.
