Abstract

The invention discloses a high performance liquid chromatography and chiral mobile phase separated hydrochloric acid daclatasvir and five optical isomers thereof. The high performance liquid chromatography and chiral mobile phase separated hydrochloric acid daclatasvir is characterized in that L-asparaginic acid, (2R, 3R)-dipropyl tartaric acid, D-(+)-Di-p-toluoyl-L-tartaric acid, (1R, 2R)-(-)-N-(p-methylphenylsulfonyl)-1, 2-diphenylethanediamine or L-valyl-L-tyrosine is used as an additive and added to the mobile phase, and a common C18 liquid chromatographic column can be utilized to effectively separate hydrochloric acid daclatasvir and five optical isomers thereof, and mutual baseline separation is achieved. The technicians in the field know that the chiral mobile phase is limited andcan only be used for separating limited compounds, and systemic theory guidance is not provided to guide any compound to be separated through the chiral mobile phase, and the chiral mobile phase for separating is only performed by 'trial and error' repeated testing and random exploring. Therefore, the method is not obvious to the technicians in the field and has the creativity as specified by thepatent law.

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 for the treatment of hepatitis C), 5 chiral isomers will be produced during the preparation of 1, 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, cR, dR...
