| 摘 要： | 目的合成二氢嘧啶脱氢酶抑制剂吉莫斯特。方法以丙二腈、原乙酸三甲酯和1,1二甲氧基三甲胺为起始原料制备1,1二氰基2甲氧基4(N,N二甲基氨基)1,3丁二烯,经体积分数为80%的冰醋酸环合得3氰基4甲氧基2(1H)吡啶酮,再经NCS氯代形成5氯3氰基4甲氧基2(1H)吡啶酮,经质量分数为48%的HBr水解得吉莫斯特。结果合成了吉莫斯特,总收率达65.6%,各步中间体结构由MS1、H NMR确证,目标产物经MS、1H NMR以及元素分析确证。结论该工艺路线成本较低,反应条件温和,操作简便,容易实现工业化生产。

| Abstract: | Objective To synthesize gimeracil,which is a potent dihydropyrimidine dehydrogenase inhibitor.Methods Gimeracil was synthesized by four steps from malononitrile,trimethyl orthoacetate and 1,1-dimethoxy-trimethylamine via condensation,cyclization,chlorination and hydrolysis reactions.Results Gimeracil was synthesized in overall yield of 65.6%,its structure was confirmed by MS,()~1H-NMR as well as elemental analysis.Intermediate compounds were confirmed by MS and()~1H-NMR.Conclusions The improved process has advantages of lower cost,mild reaction conditions,convenient work-up.It is suitable for industrial production. |
