Three new amide compounds 6, 8 and 9 were derived from diazo dye 4. 4-Hydroxy-3-methoxy-5-(2,6-dinitrophenyl) benzaldehyde 4 was reacted separately with compounds 5 and 7 to obtain 6 and 8, respectively. The amide compound 9 was synthesized by two different methods. The reaction between 6 and a diacyl chloride compound 7 gave compound 9. Also, compound 9 was produced via the reaction of compound 8 and an N-terminus compound 5. All compounds were characterized by their melting points, UV-Vis, and FTIR spectra. Moreover, the mass spectrum and elemental analysis of compound 9 were determined. All three synthesized compounds were tested against P. mirabilis, E. coli, and S. aureus at different concentrations and showed significant results.
