Synthesis, crystal structure and antibacterial properties of 6-methyl-2-oxo-4-(quinolin-2-yl)-1,2,3,4-tetrahydropyrimidine-5-carboxylate.

The synthesis and investigation of a new biologically active derivative of dihydropyrimidine are reported. The structure of the synthesized compound was investigated by X-ray single crystal diffraction method. In order to understand the molecular interactions, the Hirshfeld surface and contacts enrichment analyses were performed. The crystal packing is mainly stabilized by strong N–H⋯O hydrogen bonds and aromatic cycle stacking. Among the different types of oxygen atoms, the most electronegative had the highest propensity to form H-bonds. Biological activity of the synthesized compound was studied against E.coli , P. aeruginosa and S. aureus bacteria.
