N-[5-(2-Methylsulfonylbenzenesulfonylamino)-1H-indazol-3-yl]benzamide can be obtained as described in Example 28 from 0.5 g of N-(3-amino-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide, 3 ml of pyridine and 0.158 ml of benzoyl chloride. 435 mg of N-[5-(2-methylsulfonylbenzenesulfonylamino)-1H-indazol-3-yl)benzamide are thus obtained in the form of a pink solid which decomposes at approximately 200° C.
