실험 절차

N-(3-Furan-3-yl-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide can be obtained as described in Example 47 from of 2 g of tert-butyl 3-iodo-5-(N-tert-butoxycarbonyl-2-methylsulfonylbenzenesulfonylamino)indazole-1-carboxylate, 660 mg of 3-furanboronic acid, 80 ml of dimethylformamide, 6.4 ml of a saturated aqueous sodium hydrogencarbonate solution and 85.4 mg of tetrakis(triphenylphosphine)palladium[0]. 440 mg of N-(3-furan-3-yl-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide are thus obtained in the form of a white solid melting at 249° C. (analysis C18H15N3O5S2 % calculated C, 51.79; H, 3.62; N, 10.07; O, 19.16; S, 15.36. % found C, 51.63; H, 3.55; N, 10.00; S, 15.13).
