Reaction Steps

3-Fluoro-N-(3-hydroxy-1H-indazol-5-yl)benzenesulfonamide can be obtained as described in Example 2 from 51 mg of 5-amino-3-hydroxy-1H-indazole, 1.5 ml of pyridine and 69 mg of 3-fluorobenzenesulfonyl chloride. 6 mg of 3-fluoro-N-(3-hydroxy-1H-indazol-5-yl)benzenesulfonamide are thus obtained in the form of a white solid.
