The present invention relates to a method for differentiating and quantifying the enantiomers, thereby determining the enantiomeric purity, of darifenacin and its intermediate compounds and salts thereof. In addition, the invention relates to a method for differentiating and quantifying the enantiomers, thereby determining the enantiomeric purity of compounds of formula (I):
wherein Y is hydrogen or a substituent of the formula:
including the differentiation and quantification of compounds of formula (I) of varying enantiomeric purity from their corresponding enantiomers. The invention further relates to a process for preparing enantiomerically pure darifenacin using enantiomerically pure starting compounds which have been previously differentiated and quantified according to the method of the invention.
本发明涉及一种区分和定量达瑞那新及其中间体化合物和盐的对映体的方法,从而确定其对映异构体纯度。此外,本发明还涉及一种区分和定量式(I)化合物的对映体的方法,从而确定其对映异构体纯度,其中Y为氢或式的取代基:包括区分和定量对映异构体纯度不同的式(I)化合物及其对应的对映体。本发明还涉及一种制备对映纯达瑞那新的方法,使用之前已经根据本发明方法进行区分和定量的对映纯起始化合物。
