Provided is a method for producing a di(arylamino)aryl compound that has superior inhibitory activity against the kinase activities of EML4-ALK fusion protein and mutant EGFR protein and is useful as an active ingredient in pharmaceutical compositions for cancer treatment. The production method includes no purification step using silica gel column chromatography or no step possibly producing a mutagenic mesylate ester as a by-product, greatly improves overall yield, and is high yield and low cost and suitable for the industrial production of pharmaceutical products. Also provided is a synthetic intermediate that is useful in the production method.
提供了一种生产二(芳基氨基)芳基化合物的方法,该化合物具有优异的抑制EML4-ALK融合蛋白和突变EGFR蛋白激酶活性的活性,并可用作癌症治疗药物组合物的活性成分。该生产方法不包括使用硅胶柱层析进行纯化步骤或可能产生致突变的甲磺酸酯副产物的步骤,极大地提高了总产量,且产率高、成本低,适用于制药产品的工业生产。还提供了一种在生产方法中有用的合成中间体。
