Procedure
3-Fluoro-N-(3-iodo-1H-indazol-5-yl)benzenesulfonamide can be obtained as described in Example 2 from 230 mg of 5-amino-3-iodo-1H-indazole, 5 ml of pyridine and 173 mg of 3-fluorobenzenesulfonyl chloride. 40 mg of 3-fluoro-N-(3-iodo-1H-indazol-5-yl)benzenesulfonamide are thus obtained in the form of a cream solid melting at 189° C.
