Versuchsvorschrift
2-Methylsulfonyl-N-(3-naphthalen-2-yl-1H-indazol-5-yl)benzenesulfonamide can be obtained as described in Example 59 from 0.5 g of tert-butyl 3-iodo-5-(2-methylsulfonylbenzenesulfonylamino)indazole-1-carboxylate, 298 mg of 2-naphthaleneboronic acid, 20 ml of dimethylformamide, 1.88 ml of a saurated aqueous sodium hydrogencarbonate solution and 24.5 mg of tetrakis(triphenylphosphine)palladium[0]. 120 mg of 2-methylsulfonyl-N-(3-naphthalen-2-yl-1H-indazol-5-yl)benzenesulfonamide are thus obtained in the form of a white solid melting at 221° C. (analysis C24H19N3O4S2 % calculated C, 60.36; H, 4.01; N, 8.80; O, 13.40; S, 13.43. % found C, 60.09, H, 4.06; N, 8.55; S, 13.51).
