The synthesis of derivatives of 1,4,6-benzo[b]triazaphenothiazine, a novel aza-analog of phenothiazine, is described. The parent compound was obtained by base-catalysed condensation of 3-amino-2-mercaptopyridine with 2,3-dichloroquinoxaline in aqueous DMF. Several derivatives were also prepared by using the appropriately substituted aminomercaptopyridines and dichloro-quinoxalines. Nitration with mixed
描述了一种新型的吩噻嗪氮杂类似物1,4,6-苯并[ b ]三氮杂吩噻嗪的衍生物的合成。通过3-氨基-2-巯基吡啶与2,3-二氯喹喔啉在DMF水溶液中的碱催化缩合获得母体化合物。还通过使用适当取代的氨基巯基吡啶和二氯喹喔啉制备了几种衍生物。用硝酸和硫酸混合硝化得到相应的13-硝基-1,4,6-苯并[ b ]三氮杂吩噻嗪衍生物。通过化学证据以及对它们的红外,紫外,pmr和质谱的研究阐明了这些结构。
