N-[5-(3,5-Difluorobenzenesulfonylamino)-1H-indazol-3-yl]benzamide can be obtained as described in Example 28 from 0.15 g of N-(3-amino-1H-indazol-5-yl)-3,5-difluorobenzenesulfonamide, 13.5 ml of pyridine and 0.06 ml of benzoyl chloride. 30 mg of N-[5-(3,5-difluorobenzenesulfonylamino)-1H-indazol-3-yl)benzamide are thus obtained in the form of a cream solid melting at 246° C.
