The invention relates to an improved process for the manufacture of enantiomerically pure R-(+) or S-(+)-5-(2-aminopropyl)-2-methoxybenzene sulfonamide by resolution of (R,S)-5-(2-aminopropyl)-2-methoxybenzene sulfonamide with D-(-) or L-(+)-tartaric acid to form a mixture of diastereomeric salts, separating the diastereomeric salts by kinetic resolution in a mixture of solvent systems of the kind such as herein described, in the specified time and temperature range to provide said R-(-)-5-(2-aminopropyl)-2-methoxybenzene sulfonamide or S-(+)-5-(2-aminopropyl)-2-methoxybenzenesulfonamide with excellent chiral purity more than 99.9 %.
该发明涉及一种改进的工艺,用于通过用D-(-)或L-(+)-
酒石酸与(R,S)-5-(2-
氨基丙基)-2-
甲氧基苯磺酰胺进行拆分,以形成一种二对映异构盐混合物,通过在所述特定时间和温度范围内在类似于此处描述的溶剂系统混合物中的动力学拆分分离二对映异构盐,以提供具有优异手性纯度超过99.9%的所述R-(-)-5-(2-
氨基丙基)-2-
甲氧基苯磺酰胺或S-(+)-5-(2-
氨基丙基)-2-
甲氧基苯磺酰胺。
