  日期：——

  Chlorination with equimolar POCl3 can be efficiently achieved not only for hydroxypyrimidines, but also for many other substrates such as 2-hydroxy-pyridines, -quinoxalines, or even -amides. The procedure is solvent-free and involves heating in a sealed reactor at high temperatures using one equivalent of pyridine as base. It is suitable for large scale (multigram) batch preparations.

  使用等摩尔量的POCl3对羟基嘧啶进行氯化不仅是有效的，而且对许多其他底物，如2-羟基吡啶、喹唑啉或甚至酰胺也是如此。该过程是无溶剂的，涉及在密封反应器中高温加热，使用一当量的吡啶作为碱。它适用于大规模（多克级）批次制备。
