The invention relates to a method for the purification of L-hercynine. Said method for the purification of L-hercynine, from a reaction mixture resulting from the reaction of L-histidine, in controlled pH conditions, with a methylating agent Me X in a polar solvent or a mixture of polar solvents, at room temperature, is characterised in that it comprises at least one step of separating the organic products from the inorganic salts formed during the reaction by electrodialysis. This method allows the L-hercynine losses to be limited during the purification.
本发明涉及一种L-赫西宁的纯化方法。该方法是从
L-组氨酸反应混合物中,通过在控制的pH条件下,使用甲基化试剂Me X在极性溶剂或极性溶剂混合物中,在室温下进行反应,并至少包括一步通过电渗析分离有机产物与反应中形成的
无机盐。该方法可在纯化过程中限制L-赫西宁的损失。
