Provided is a method for producing an antibody-drug conjugate intermediate by addition of acid. An acid additive is used to convert the monomethyl auristatin derivative into a salt thereof to participate in the reaction. The addition of the acid additive can significantly improve the yield of the final product. In addition, the low price of the acid additive greatly reduces the production cost of the final ADC product. Moreover, the method of the present invention adopts a one-step preparation process, in addition to a higher yield of the final product, not only reducing the cost of the consumables, labor, equipment, site, raw materials and the like in the production, but also greatly reducing the production of the waste liquid, and thus reducing production costs and improving production efficiency, and making the method suitable for industrial large-scale production.
本发明提供了一种通过加酸生产抗体-药物共轭中间体的方法。使用酸添加剂将单甲基金丝桃素衍生物转化为其盐,以参与反应。添加酸添加剂可显著提高最终产品的产量。此外,酸添加剂价格低廉,大大降低了 ADC 最终产品的生产成本。而且,本发明方法采用一步制备工艺,除了最终产品收率较高外,不仅降低了生产中的耗材、人工、设备、场地、原料等成本,还大大减少了废液的产生,从而降低了生产成本,提高了生产效率,适合工业化大规模生产。
