| 摘要 |
A method for producing ethyl (3R, 5S, 6E) -7-[2-cyclopropyl-4-(4-fluorophenyl)qunoline-3-yl]-3, 5-dihydroxy-6- heptanoate from a solution containing a mixture of optical isomers of ethyl 6E-7-[2-cyclopropyl-4-(4-fluorophenyl)qunoline-3-yl]-3,5-dihydroxy- 6-heptanoate by means of the liquid chromatography using a packing material having a carrier and, carried thereon, a polysaccharide derivative, characterized in that a part or all of the hydrogen atoms of the hydroxyl groups and amino groups of the polysaccharide derivative are substituted with one or more substituents, such as a carbamoyl group wherein one hydrogen atom is substituted with an aromatic group having a specific alkyl group. The method allows the production of the above (3R, 5S, 6E) isomer with enhanced productivity compared to a conventional method.
