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.
描述了6-溴-1-乙基-2,4-二氧代-1,2,3,4-四氢喹唑啉及其苯甲酰基和苄基衍生物的合成。采用一种涉及2,5-二溴苯甲酸新合成方法，从邻氨基苯甲酸合成了未报道的5-溴-N-苯基邻氨基苯甲酸。N-苯基邻氨基苯甲酸和N-对甲苯基邻氨基苯甲酸的直接溴化分别得到三溴和二溴衍生物。
