N-Phenyl-5-(2-methylsulfonylbenzenesulfonylamino)-1H-indazole-3-carboxamide can be obtained as described in Example 2 from 40 mg of N-phenyl-5-amino-1H-indazole-3-carboxamide, 4 ml of pyridine and 40 mg of 2-methylsulfonylbenzenesulfonyl chloride. 50 mg of N-phenyl-5-(2-methylsulfonylbenzenesulfonylamino)-1H-indazole-3-carboxamide are thus obtained in the form of a pale yellow solid melting at 258° C. (analysis C21H18N4O5S2.0.48H2O, % calculated C, 53.61; H, 3.86; N, 11.91; O, 17.00; S, 13.63. % found C, 53.17; H, 3.48; N, 11.58; S, 14.08).
