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.
