The invention relates to 3,3-diarylpropylamines derivatives and processes for producing them. More particularly, it relates to the preparation of pure tolterodine or a pharmaceutically acceptable salt thereof and pharmaceutical compositions that include the pure tolterodine or a pharmaceutically acceptable salt thereof. It also relates to a novel 3,3diarylpropylamine derivative, referred to as tolterodine dimer. Chemically, tolterodine dimer is N,N-di-[3-[2-hydroxy-5-methylphenyl]-3-phenylpropyl]isopropylamine and has structural Formula (I), The invention also relates to use of pure tolterodine or tolterodine dimer as reference standards or reference markers for checking the purity of tolterodine.
本发明涉及3,3-二芳基丙胺衍生物及其制备方法。更具体地说,涉及纯度高的托吡酯或其药学上可接受的盐的制备,以及包括纯托吡酯或其药学上可接受的盐的制药组合物。还涉及一种新型的3,3-二芳基丙胺衍生物,称为托吡酯二聚体。在化学上,托吡酯二聚体是N,N-二-[3-[2-羟基-5-甲基苯基]-3-苯基丙基]异丙胺,其结构式为(I)。本发明还涉及将纯托吡酯或托吡酯二聚体用作参考标准或参考标记物,以检查托吡酯的纯度。
