摘要
通过间羟基苯硼酸与2,4-二氯嘧啶的Suzuki反应及其后酚羟基的烷基化得到4-芳基-2-氯嘧啶衍生物.然后,采用Pd(PPh3)4/dppf催化剂,在温和的条件下实现了4-芳基-2-氯嘧啶类化合物和芳香胺的偶联.合成了3个结构新颖的2-芳氨基嘧啶类化合物.中间体及产物的结构均经由IR,1HNMR,13CNMR,MS和元素分析表征而予以证实.
4-(m-Substituted phenyl)-2-choloro-pyrimidines were prepared by Suzuki coupling reaction of 3-hydroxyphenylboronic acid with 2,4-dichloropyrimidine followed by alkylation of the hydroxyl group, which were effectively aminated by arylamine under catalysis of Pd(PPh3)4/dppf. Three novel 2- 2-(substituted anilino)pyrimidine derivatives were thus conveniently synthesized. The structures of all the synthesized compounds were fully characterized by IR, ^1H NMR, ^13C NMR, mass spectra and elemental analysis.
