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.
提供了一种通过添加酸来制备抗体药物结合物中间体的方法。使用酸添加剂将单甲基奥利斯塔汀衍生物转化为其盐以参与反应。添加酸添加剂可以显著提高最终产品的产量。此外,酸添加剂的低价格大大降低了最终ADC产品的生产成本。此外,本发明的方法采用一步法制备过程,除了最终产品产量更高外,不仅减少了生产中的耗材、劳动力、设备、场地、原材料等成本,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,并使该方法适用于工业大规模生产。
