A process for the preparation of solifenacin and/or the pharmaceutically acceptable salts thereof of high pharmaceutical purity is characterized in that 3-(R)-quinuclidinoloxy anion generated in situ from 3-(R)-quinuclidinol in a presence of strong base in polar organic solvent is subject to acylation with (S)-1 -phenyl-1,2,3, 4-tetrahydroisoquinolinecarbonyl chloride of chemical purity at least 98%, while maintaining constant anion excess in a reaction mixture, and after reaction completion solifenacin base is optionally transformed into solifenacin salt according to standard procedures. (S)-1-Phenyl-1,2,3,4-tetrahydroisoquinolinecarbonyl chloride of chemical purity at least 98% is obtained in a reaction of (S)-1-phenyl-1,2,3, 4- tetrahydroisoquinoline and molar excess of phosgene in a presence of tertiary aromatic amine in aromatic hydrocarbon, and isolated in a crystalline form.
一种制备高纯度药物溶剂那非和/或其药用可接受盐的方法,其特征在于在极性有机溶剂中,在强碱的存在下,由3-(R)-喹诺酮醇生成的3-(R)-喹诺酮氧负离子在反应混合物中保持恒定的过量阴离子的情况下,与至少98%化学纯度的(S)-1-苯基-1,2,3,4-四氢异喹啉羰基氯化物发生酰基化反应,反应完成后,溶剂那非碱可选择地按标准程序转化为溶剂那非盐。至少98%化学纯度的(S)-1-苯基-1,2,3,4-四氢异喹啉羰基氯化物是通过(S)-1-苯基-1,2,3,4-四氢异喹啉和过量的光气在芳香烃的存在下,以及在结晶形式中分离。
