目的:改进苯甲酸阿格列汀的合成工艺。方法以6—氯尿嘧啶为起始原料,先与碘甲烷反应合成3—甲基—6—氯尿嘧啶,继而在无机碱的参与下与2—溴甲基苄腈反应得2—(6—氯—3甲基—2,4—二氯代—3,4—二氢—2H—嘧啶—1—基甲基)—苄腈,然后再在无机碱的存在下与( R)—3—氨基哌啶二盐酸发生取代反应,最后与苯甲酸成盐得苯甲酸阿格列汀。结果合成得到苯甲酸阿格列汀,总收率达到57.09%,纯度为99.6%。结论该工艺经过改进,降低了毒害,成本降低,经济环保,适合工业化生产。
目的:改進苯甲痠阿格列汀的閤成工藝。方法以6—氯尿嘧啶為起始原料,先與碘甲烷反應閤成3—甲基—6—氯尿嘧啶,繼而在無機堿的參與下與2—溴甲基芐腈反應得2—(6—氯—3甲基—2,4—二氯代—3,4—二氫—2H—嘧啶—1—基甲基)—芐腈,然後再在無機堿的存在下與( R)—3—氨基哌啶二鹽痠髮生取代反應,最後與苯甲痠成鹽得苯甲痠阿格列汀。結果閤成得到苯甲痠阿格列汀,總收率達到57.09%,純度為99.6%。結論該工藝經過改進,降低瞭毒害,成本降低,經濟環保,適閤工業化生產。

Pbjective To improve synthetic process of alogliptin benzoate. Methods Alogliptin benzoate was synthe-sized from 6—chlorine uracil and iodomethane to give 3 —methyl—6 —chlorine uracil,then in the presence of inorganic base with 2—bromine methyl benzonitrile reaction to 2—(6—methyl chloride—3—2,4—dichloro generation—3,4—di-hydro—2 h—pyrimidine—1—methyl)—benzonitrile,which was subjected to displacement with( R)—3—aminopiperidine in the presence of inorganic base. And then salified with benzoic acid to obtain alogliptin benzoate. ResuIts Alogliptin ben-zoate was synthesized. The overall yield was 57. 09%,and its purity was 99. 6%. ConcIusion The improvement reduced toxic,and was economic and environmental. It was suitable for industrial production.
