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.
本发明涉及一种制备取代N-(5-苯磺酰基-1H-吲哚-3-基)-苯甲酰胺的过程,以及该过程中的有用中间化合物。这些衍生物在WO2008/074749中有描述和申请,该专利还公开了它们的制备方法。本发明的工艺允许以高收率和纯度,并且在有限步骤内获得所需产品。合成从5-碘-1H-吲哚-3-基胺开始,并包括关键步骤,即活化苯甲酸与5-苯基硫基-1H-吲哚-3-基胺支架的偶联,随后是硫原子的氧化,然后进行进一步的官能团转化,从而得到所需的产物。根据本发明的工艺制备的化合物具有蛋白激酶抑制活性,更具体地说是IGF-1R或ALK抑制活性。因此,这些化合物在治疗各种癌症、细胞增殖障碍和与蛋白激酶相关的疾病方面非常有用。
