An effective method has been developed for the synthesis of 2-amino-4-aryl-6-chloropyridine-3,5-dicarbonitriles from 3-arylcyclopropane-1,1,2,2-tetracarbonitriles by treating the starting materials with sodium hydride in anhydrous DMF, followed by HCl in isopropanol.
开发了一种由3-芳基环丙烷-1,1,2,2-四甲腈合成2-氨基-4-芳基-6-氯吡啶-3,5-二甲腈的有效方法,通过用氢化钠处理起始原料。无水DMF,然后是异丙醇中的HCl。
