It plays an important role in exploring new EGFR inhibitors. There are lots of 4-anilinoquinazoline derivatives were designed and synthesized as EGFR inhibitors. And gefitinib and erlotinib were two 4-anilinoquinazolines using as anticancer drugs for the notable EGFR inhibitor activity. There are many reports about the synthesis of 4-anilinoquinazoline derivatives. And these synthesis works were summarized to two main strategies, using quinazolone as key intermediate or forming 4-anilinoquinazoline ring directly. Benzaldehyde and its derivatives were usually selected as starting materials and nitro reaction and its reduction were enrolled in the two strategies. To avoid these two steps in synthesis work, we have designed and proved a novel strategy with only five steps in our previous work. Aniline and its derivatives were used as starting materials and isatin and its derivatives were synthesized as key intermediates. Comparing with the reported strategies, our novel route was more convenient and effective for its facility post purification process and high total yields. In this work, almost all the works of synthesis of 4-anilinoquinazolines were reviewed and the advantaged and disadvantaged of each synthetic work were also elucidated. It was helpful to study the synthesis of 4-anilinoquinaolines and to seek new active compounds. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
