摘要: A 9-hydroxy or 9-acyloxy group can be added to a pyridopyrimidinone ring structure by a process comprising acylating a compound of formula (5) under Vilsmeier-Haack or Friedel-Crafts conditions to form a compound (6); and transforming with a peroxo-compound to obtain the compound (1). R represents hydrogen or a C1-C20 acyl group. The process is useful in the synthesis of paliperidone and derivatives.

摘要: A compound of formula (7.2) or an acid addition salt thereof. The compound can be used as a reference standard for monitoring the presence thereof in a paliperidone sample, including monitoring the completion of a paliperidone reaction. Reduction in the amount of the compound in paliperidone can be achieved by crystallization in the presence of a hydride reductant.
摘要翻译: 式(7.2)的化合物或其酸加成盐。 该化合物可以用作监测其在帕培培酮样品中的存在的参考标准,包括监测帕培培酮反应的完成。 在利培酮中化合物的量的减少可以通过在氢化物还原剂存在下结晶来实现。
