A novel approach to prepare 4-anilinoquinazoline derivatives based on the transformation of indoline-2,3-dione to formamidine was developed. The processes with this approach are simple, efficient, and environmentally friendly. The efficiency of this approach was evaluated by synthesizing 17 4-anilinoquinazolines and comparing the obtained yields with those achievable through conventional synthetic
开发了一种基于吲哚啉-2,3-二酮向甲am的转化制备4-苯胺基喹唑啉衍生物的新方法。使用这种方法的过程简单,高效且对环境友好。通过合成17种4-苯胺基喹唑啉并将获得的收率与通过常规合成方法可获得的收率进行比较,评估了该方法的效率。这是第一次合成化合物8d,8e,8h和13b - f。观察到这些化合物的IR和UV光谱的特征以及它们的取代基对光谱的影响。
