Reaction Steps
3-Fluoro-N-(3-methylsulfonylamino-1H-indazol-5-yl)benzenesulfonamide can be obtained as described in Example 2 from 0.1 g of 5-amino-3-methylsulfonylamino-1H-indazole, 5 ml of pyridine and 83 mg of 3-fluorobenzenesulfonyl chloride. 30 mg of 3-fluoro-N-(3-methylsulfonylamino-1H-indazol-5-yl)benzenesulfonamide are thus obtained in the form of a beige solid melting at 230° C. (analysis C14H13FN4O4S2.0.57H2O % calculated C, 43.75; H, 3.41; F, 4.94; N, 14.57; O, 16.65; S, 16.68. % found C, 43.75; H, 2.86; N, 14.77; S, 15.93).
