Study on Syntheses and Antimicrobial Activities of Derivatives of 3-Amino-2-methyl-quinazolin-4-(3H)-one| Chapter 10 | New Innovations in Chemistry and Biochemistry Vol.7

This work produced 3-amino-2-methyl-quinazolin-4-(3H)-one (1) by reacting N-acetyl anthranilic acid with acetic anhydride and then treating the combination with hydrazine hydrate in pyridine. When compound 1 is reacted with chloro acetyl chloride, it produces 3-chloroethanoylamino-2-methyl-quinazolin-4-(3H)-one(2). The final compounds 4a-g were
