Disclosed herein is a method of preparing solifenacin or a salt thereof, including the steps of: (a) reacting (R)-quinuclidinol with bis(pentafluorophenyl)carbonate in an organic solvent to prepare a solifenacin intermediate, (3R)-1-azabicyclo[2,2,2]oct-3-yl pentafluorophenylcarbonate, and (b) reacting the solifenacin intermediate with (1S)-1-phenyl-1,2,3,4-tetrahydroisoquinoline in an organic solvent to prepare solifenacin. The method is advantageous in that high-purity solifenacin or a salt thereof can be simply and efficiently prepared with high yield using a novel intermediate.
本文公开了一种制备索利那辛或其盐的方法,包括以下步骤:(a)在有机溶剂中将(R)-喹诺酚与双(五氟苯基)碳酸酯反应,制备索利那辛中间体,(3R)-1-氮杂双环[2,2,2]辛-3-基五氟苯基碳酸酯,(b)在有机溶剂中将索利那辛中间体与(1S)-1-苯基-1,2,3,4-四氢异喹啉反应,制备索利那辛。该方法的优点在于可以简单高效地利用新型中间体高产率地制备高纯度的索利那辛或其盐。
