Abstract

The invention discloses a high performance liquid chromatography chiral mobile phase method for separation of daclatasvir hydrochloride and five optical isomers thereof. The daclatasvir hydrochlorideand the five optical isomers thereof can be effectively separated by adding of L-aspartic acid, (2R, 3R) bis-n-propyl tartaric acid, (+)-di-p-toluoyl-D-tartaric acid, and (1R, 2R)-(-)-N-(p-toluenesulfonyl)-1,2-diphenylethylenediamine or L-valyl-L-tyrosine as additives to a mobile phase by use of a common C18 liquid chromatography column, and baseline resolution of every two of the daclatasvir hydrochloride and the five optical isomers thereof can be achieved. Persons skilled in the art know that a chiral mobile phase method is very limited in that and only a limited number of compounds can beseparated, no systematic theory can guide which compounds can be separated by the chiral mobile phase method, and only a trial-and-error method can be used for repeatedly trying and groping without rules. Accordingly, the high performance liquid chromatography chiral mobile phase method has obvious creativity prescribed by the patent law for the persons skilled in the art.

Description

technical field [0001] The invention belongs to the field of medicine and relates to drug analysis, in particular to a high-performance liquid chromatography chiral mobile phase method for separating daclatasvir hydrochloride and five optical isomers thereof. Background technique [0002] Daclatasvir dihydrochloride (1), chemical name N, N'-[[1,1'-biphenyl]-4,4'-diylbis[1H-imidazole-5,2-diyl -(2S)-2,1-pyrrolidinediyl[(1S)-1-(1-methylethyl)-2-oxo-1,2-ethanediyl]]]dicarbamic acid dimethyl Ester dihydrochloride is a non-structural protein 5A (NS5A) inhibitor and an anti-hepatitis C virus drug. [0003] 1 (type aS, bS, cS, dS) contains 4 chiral centers. According to literature reports (Chinese patent, CN101778841A, method for synthesizing compounds used to treat hepatitis C), 5 chiral isomers will be produced during the preparation of 1, which are respectively 2(aR, bS, cS, dS type), 3 (type aS, bS, cR, dS), 4 (type aR, bS, cS, dR), 5 (type aS, bR, cR, dS) and 6 (type aR, bR,...
