The derivatives of Propionic Acid of Quinazoline were synthesized. It was prepped by reaction of distinct amino acids with 7-nitro-2-phenyl-4H-benzo [1,3]oxazin-4-one. Configurations of same compounds have been appraised by NMR, MASS and IR spectral analysis. Synthesized compounds were screened with against following pathogenic bacteria Staphylococcus aureus, Staphylococcus pneumoniae, Pseudomonas aeruginosa, Escherichia coli and Klebsiella pneumonia. We used 500ppm concentration in DMSO for their antibacterial activity by Kirby-Baur disk diffusion method.
