-
Paragraph 0028-0030, (2018/10/19)
The invention discloses a preparation method of high-purity fudosteine, and belongs to the technical field of synthesis of pharmaceutical compounds. The preparation method is characterized in that with 3-halogenated propyl acetate or 3-halogenated propyl propionate and L-cysteine as starting materials, a fudosteine crude product is prepared through a reaction in an aqueous alkali solution, and high-purity fudosteine is obtained by refining the fudosteine crude product. The preparation method has the advantages that the reaction conditions are mild, the reaction process is simple, the yield ishigh, the cost is low, the requirement that the content of unknown impurities is lower than 0.1% can be met, and the preparation method is suitable for industrial application.
