N-Methyl-5-(3-fluorobenzenesulfonylamino)-1H-indazole-3-carboxamide can be obtained as described in Example 2 from 40 mg of N-methyl-5-amino-1H-indazole-3-carboxamide, 1.2 ml of pyridine and 40 mg of 3-fluorobenzenesulfonyl chloride. 20 mg of N-methyl-5-(3-fluorobenzenesulfonylamino)-1H-indazole-3-carboxamide are thus obtained in the form of an off-white solid melting above 260° C.
