    • The present invention relates to a process for the preparation of substituted N-(5-benzenesulfonyl-1 H-indazol-3-yl)-benzamides and to the useful intermediate compounds of such process. Such derivatives are described and claimed in WO2008/074749, which also discloses processes for their preparation. The process of the present invention allows to obtain the desired products in high yields and purity and with a limited number of steps. The synthesis starts from 5-iodo-1 H-indazol-3-ylamine and comprises, as the key steps, the coupling of an activated benzoic acid with a 5-phenylsulfanyl-1 H-indazol-3-ylamine scaffold and the subsequent oxidation of the sulfur atom, followed by further functional group transformations, which furnish the desired products. The compounds prepared according to the process of the present invention are endowed with protein kinase inhibiting activity and, more particularly, IGF-1R or ALK inhibiting activity. The compounds are therefore useful in the treatment of a variety of cancers, cell proliferative disorders and diseases associated with protein kinases.
    • 本发明涉及制备取代的N-(5-苯磺酰基-1H-吲唑-3-基) - 苯甲酰胺的方法和该方法的有用的中间体化合物。 在WO2008 / 074749中描述和要求保护这些衍生物,其也公开了它们的制备方法。 本发明的方法允许以高产率和纯度和有限数量的步骤获得所需的产物。 合成从5-碘-1H-吲唑-3-基胺开始,并且作为关键步骤包括活化的苯甲酸与5-苯基硫烷基-1H-吲唑-3-基胺支架的偶联和随后的氧化 的硫原子,随后进一步的官能团转化,其提供所需的产物。 根据本发明的方法制备的化合物具有蛋白激酶抑制活性,更具体地,赋予IGF-1R或ALK抑制活性。 因此,这些化合物可用于治疗多种癌症,细胞增殖性疾病和与蛋白激酶相关的疾病。
