    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: 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.
