Synthesis of Dinotefuran Metabolite UF
GUO Hui, CHEN Wu-lian (Anpel Laboratory Technologies (Shanghai) Inc., Shanghai 201600, China)
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.
