N-[5-(3,5-Difluorobenzenesulfonylamino)-1H-indazol-3-yl]acetamide can be obtained as described in Example 28 from 0.1 g of N-(3-amino-1H-indazol-5-yl)-3,5-difluorobenzenesulfonamide, 9 ml of pyridine and 0.024 ml of acetyl chloride. 338 mg of N-[5-(3,5-difluorobenzenesulfonylamino)-1H-indazol-3-yl)-acetamide are thus obtained in the form of a cream solid melting at 268° C.
