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, 1H NMR, 13C NMR, MS和元素分析表征而予以证实.

关键词: Pd(PPh3)4, dppf, 偶联反应, 2-芳氨基嘧啶

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.

Key words: dppf, 2-(substituted anilino)pyrimidine, coupling reaction, Pd(PPh3)4
