title: Synthesis and biological activity of certain derivatives of 2,4-dioxo-1,2,3,4-tetrahydroquinazoline. Part 2.
abstract: The synthesis of 6-bromo-1-ethyl-2,4-dioxo-1,2,3,4-tetrahydroquinazoline, its benzoyl and its benzyl derivatives is described. The unreported 5-bromo-N-phenyl-anthranilic acid was synthesized from anthranilic acid adopting a procedure, which involved a novel synthesis of 2,5-dibromobenzoic acid. Direct bromination of N-phenylanthranilic acid and N-p-tolyl-anthranilic acid afforded the tribromo-and dibromoderivatives respectively.
