The present invention relates to a process for the preparation of Solifenacin succinate by condensing a compound of formula (IVb) with (RS)-3-quinuclidinol, wherein, R represents methyl, ethyl, isopropyl; to produce a diastereomeric mixture of (1S)-3,4-dihydro-1-phenyl-2(1H)-isoquinolinecarboxylic acid (3RS)-1-azabicyclo[2.2.2]oct-3-yl ester, which is treated with succinic acid in a solvent or mixture of solvents to produce optically pure Solifenacin succinate, Formula (X).
这项发明涉及一种通过将式(IVb)化合物与(RS)-3-喹诺啉醇缩合来制备索利那辛琥酸盐的方法,其中,R代表甲基、乙基、异丙基;以产生(1S)-3,4-二氢-1-苯基-2(1H)-
异喹啉羧酸(3RS)-1-
氮杂双环[2.2.2]辛-3-基酯的对映体混合物,该混合物与
琥珀酸在溶剂或溶剂混合物中反应,以产生光学纯的索利那辛琥酸盐,
化学式(X)。
