A method of performing isolation and purification of bedaquiline (la) from a mixture of stereoisomers of 6-bromo-2-methoxy-quinolin-3-yl)-4-dimethylamino-2-(l-naphthyl)-l- phenyl-butan-2-ol identified as I-rac, being a mixture of the stereoisomers of formulae la, lb, and II-rac, being a mixture of the stereoisomers of formulae Ila, lib, with any ratio of individual constituents of the mixture, wherein said mixture is dissolved together with derivatives of 1,3 -propanediol hydrogen phosphate of formula IV, wherein R1, R2, and R3 independently stand for hydrogen, a halogen, C1-C6 alkyl, aryl, naphthyl, phenyl and preferably a halogenated phenyl or phenyl substituted in any way, and the resulting salt is crystallized.
从被鉴定为I-rac的6-溴-2-甲氧基喹啉-3-基)-4-二甲基氨基-2-(1-萘基)-1-苯基-丁-2-醇的立体异构体混合物中分离和纯化bedaquiline(la)的方法,该混合物是由公式la,lb的立体异构体混合物和II-rac的公式Ila,lib的立体异构体混合物组成,其中混合物的各个成分之间的比例可以任意,所述混合物与公式IV的1,3-丙二醇氢磷酸盐衍生物一起溶解,其中R1,R2和R3独立地代表氢,卤素,C1-C6烷基,芳基,萘基,苯基,最好是卤代苯基或以任何方式取代的苯基,并结晶得到所述盐。
