摘 要:研究了一种全新的呋虫胺代谢物UF的合成方法,即以N-甲基-1-咪唑甲酰胺和3-氨基甲基四氢呋喃为原料,在有机碱催化下室温反应得到呋虫胺代谢物UF。考察了反应的影响因素,确定了优化反应条件:n(N-甲基-1-咪唑甲酰胺)∶n(3-氨基甲基四氢呋喃)=1.0∶1.0,催化剂使用三乙胺或吡啶,n(催化剂)∶n(N-甲基-1-咪唑甲酰胺)=1.1∶1.0,反应温度为25 ℃,反应时间为18 h,优化条件下,收率达90.5%。产品结构和纯度经核磁共振波谱、质谱和高效液相色谱等仪器表征确定,呋虫胺代谢物UF的纯度>98.0%。该化合物可以作为高纯标准品,用于呋虫胺及其代谢物的残留检测。

Abstract:A novel synthetic method of dinotefuran metabolite UF was investigated. The dinotefuran metabolite UF was synthesized from N-methyl-1-imidazolamide and 3-aminomethyltetrahydrofuran using organic base as catalyst. The influencing factors of reaction were investigated and the optimal reaction conditions were determined. Experimental results indicated the optimal condition as followings: the molar ratio of N-methyl-1-imidazolamide to 3-aminomethyltetrahydrofuran was 1.0∶1.0; the catalyst was triethylamine or pyridine, and the molar ratio of catalyst to N-methyl-1-imidazolamide was 1.1∶1.0; the reaction temperature was room temperature; the reaction time was 18 h. Under the above conditions, a yield of the dinotefuran metabolite UF was up to 90.5%. The structure and chemical purity of UF were identified by NMR, MS and HPLC. The chemical purity of dinotefuran metabolite UF was higher than 98.0%. The results showed that the dinotefuran metabolite UF could be used as high purity standard in the determination of dinotefuran and metabolite residue.
