N-(3-Chloro-1H-indazol-5-yl)-3-fluorobenzenesulfonamide can be obtained as described in Example 1 from 0.18 g of 5-amino-3-chloro-1H-indazole, 20 ml of tetrahydrofuran, 0.25 ml of triethylamine and 0.23 g of 3-fluorobenzenesulfonyl chloride. 0.13 g of N-(3-chloro-1H-indazol-5-yl)-3-fluorobenzenesulfonamide is thus obtained in the form of a yellow foam which decomposes at approximately 80° C.
