摘要
目的:对目前米格列奈钙的合成路线进行优化,以获得可用于工业生产的工艺路线。方法:以(S)-2-苄基丁二酸和CDI为起始原料,制得活性酰胺后与顺式全氢异吲哚盐酸盐反应,再与氯化苄成酯后进行提纯精制,脱苄基后钙化成盐得到米格列奈钙。结果:所得米格列奈钙经HPLC检测纯度达到99.88%以上,总收率为24.46%。结论:该合成路线操作简单,收率较高,产品纯度高,适合工业化生产。
Objective: To optimize the current synthesis routes for developing a new synthetic route for mitiglinide calcium production. Methods:(S)-2-benzylsuccinic acid and CDI were used as the starting materials to get the active amide. Then the active amide was reacted with the hydrochloride salt of cis-hexahydroisoindoline and benzyl chloride to get purified benzyl ester; thereafter,debenzylation and calcification were done to get mitiglinide calcium. Results: Mitiglinide calcium was synthesized with a total yield of 24. 46%,and the purity was 99. 88% determined by HPLC. Conclusion: This synthetic process is easy to operate with high yield and purity, and suitable for industrial production.
