A series of substituted aliphatic nitriles have been trimerized to their corresponding pyrimidine structures under solvent-free conditions in the presence of catalytic quantities of potassium tert-butoxide using a focused microwave reactor. Multigram quantities of the corresponding 4-aminopyrimidines have been prepared in high yields and purity following a simple and scaleable protocol.
在聚焦微波反应器中，在催化量的叔丁醇钾存在下，一系列取代脂肪腈在无溶剂条件下三聚化为相应的嘧啶结构。按照简单且可扩展的方案，已高收率和高纯度地制备了多克量的相应4-氨基嘧啶。
