실험 절차

N-[3-(4-Dimethylaminophenyl)-1H-indazol-5-yl]-2-methylsulfonylbenzenesulfonamide can be obtained as described in Example 59 from 1 g of tert-butyl 3-iodo-5-(2-methylsulfonylbenzenesulfonylamino)indazole-1-carboxylate, 570 mg of 4-dimethylaminophenylboronic acid, 40 ml of dimethylformamide, 3.2 ml of a saturated aqueous solution of sodium hydrogencarbonate and 50 mg of tetrakis(triphenylphosphine)palladium[0]. 200 mg of N-[3-(4-dimethylaminophenyl)-1H-indazol-5-yl]-2-methylsulfonylbenzenesulfonamide are thus obtained in the form of a yellow solid melting above 260° C. (analysis C22H22N4O4S2 % calculated C, 56.15; H, 4.71; N, 11.91; O, 13.60; S, 13.63. % found C, 55.74; H, 4.81; N, 12.03; S, 13.34).
