5-正戊基-2-(对氰基苯基)嘧啶的合成

Synthesis of 5-n-pentyl-2-(4'-cyanophenyl) pyrimidine

报导了一种合成５－烷基－２－（对氰基苯基）嘧啶化合物的新方法。缩合形成嘧啶环的两个前体化合物分别是ａ－烷基－Ｂ－烷氧基丙烯醛和４－乙氧酰基苯甲脒盐酸盐。经多步反应合成了前体化合物，缩合成嘧啶环并实现了嘧啶衍生物之间的官能团转换。所合成的化合物有较好的光、热和化学稳定性，是一种性能较好的介晶材料。

A new synthetic method for 5-n-pentyl-2-(4' -cyano-phenyl) pyrimidine is reported. There are two basic synthetic composition: 2pentylacrolein and 4-ethoxycarbonyl benzoicamidehydrochlorie. The syn- thesis of these compounds, their cyclizative condensation and the transformation of the function groups were completed by a multistep synthesis route. The title compound is colourless, thermo and photo-chemically stable. It can be used as a novel mesomorphic material.
