実験手順
2-Methylsulfonyl-N-(3-thiophen-2-yl-1H-indazol-5-yl)-benzenesulfonamide can be obtained as described in Example 47 from 1.5 g of tert-butyl 3-iodo-5-(N-tert-butoxycarbonyl-2-methylsulfonylbenzenesulfonylamino)indazole-1-carboxylate, 339 mg of 2-thiopheneboronic acid, 50 ml of dimethylformamide, 4.8 ml of a saturated aqueous sodium hydrogencarbonate solution and 64 mg of tetrakis(triphenylphosphine)palladium[0]. 350 mg of 2-methylsulfonyl-N-(3-thiophen-2-yl-1H-indazol-5-yl)benzenesulfonamide are thus obtained in the form of an ochre solid melting at 246° C. (analysis C18H15N3O4S3 % calculated C, 49.87; H, 3.49; N, 9.69; O, 14.76; S, 22.19. % found C, 49.82; H, 3.67; N, 9.08; S, 20.42).
