专利号:WO-2025086625-A1 优先权日:2023-10-26 标题 :Synthesis method for deuterated tinidazole 发明人:MEI SHU; GUO HUI; CHEN WULIAN 权利人:ANPEL LABORATORY TECH SHANGHAI INC 摘要:The present invention relates to a synthesis method for a deuterated tinidazole. The deuterated tinidazole is as represented by formula I, wherein one or more of R 1 -R 5 are deuterium, and the rest is hydrogen. The synthesis method comprises the step of oxidizing an intermediate B with m-chloroperoxybenzoic acid to prepare the deuterated tinidazole, wherein the oxidation is carried out under low-temperature and alkaline conditions; and the intermediate B is as represented by formula II. By using the synthesis method of the present invention, the problems of deuterium shedding and isotope dilution in the reaction process can be avoided, and the stable isotope-labeled deuterated tinidazole with the isotope abundance of > 98% is obtained with a higher yield. The prepared deuterated tinidazole can be used as an isotope internal standard reagent for the quantitative detection of tinidazole, which, for example, can be used to detect residual tinidazole in meat products by means of an isotope internal standard method, and has the advantages of having high recovery efficiency from a matrix, and being environmentally friendly and safe.
