Novel quinazolinone derivatives: Synthesis and Antimicrobial Activity

Abstract: This work involves to synthesis novel organic compounds and studies their pharmacological. Approach: The title compound quinazolinone derivatives were prepared by reacting 3 amino of 3-amino-2-methylquinazolin-4(3H)-one (first) with various aldehydes and ketones, and second coupling through diazonium salts with resorcinol or with ethylacetoacetate then cyclized with hydrazine. The starting material 3-amino-2-methylquinazolin-4(3H)-one was synthesized by reacting hydrazine with 2-methyl-4H-benzo[d
