Abstract

The invention discloses a separation method of a blonanserin intermediate IV and other intermediates by high performance liquid chromatography. The separation method selects octylsilane chemically bonded and silica as a chromatographic column of a filling agent (250mm multiplied by 4.6mm, 5mum), adopts a buffer solution and an organic modifier with different proportions as flowing phase, and the blonanserin intermediate IV and other intermediates which has the similar polarity with the blonanserin intermediate IV can be separated under the normal temperature by gradient elution, so that the accurate control of the quality of blonanserin can be realized.

Description

technical field [0001] The invention relates to a high-performance liquid chromatography separation method, in particular to a high-performance liquid chromatography method for effectively separating blonanserin intermediate IV from other intermediates by adopting a gradient elution method. Background technique [0002] Blonanserin is an atypical antipsychotic with fewer side effects than other antipsychotics. Molecular formula of blonanserin intermediate IV: C 17 h 17 FClN, the chemical name is 2-chloro-4-(4-fluorophenyl)-5,6,7,8,910-hexahydrocyclooctano[b]pyridine, and the structural formulas of intermediates I, II, III and IV are as follows : [0003] [0004] Intermediate Ⅰ [0005] [0006] Intermediate Ⅱ [0007] [0008] Intermediate III [0009] [0010] Intermediate IV [0011] In order to effectively separate blonanserin intermediate IV from other intermediates and accurately control the quality of blonanserin intermediates, the current high-effi...
