反応手順
2-Methylsulfonyl-N-[3-(5-methoxy-1H-indol-2-yl)-1H-indazol-5-yl]benzenesulfonamide can be obtained as described in Example 47 from 1.77 g of tert-butyl 3-iodo-5-(N-tert-butoxycarbonyl-2-methylsulfonylbenzenesulfonylamino)-indazole-1-carboxylate, 1.52 g 1-(tert-butoxycarbonyl)-5-methoxy-indole-2-boronic acid, 70 ml of dimethyl-formamide, 5.65 ml of a saturated aqueous sodium hydrogencarbonate solution and 151 mg of tetrakis(triphenylphosphine)palladium[0]. 250 mg of 2-methylsulfonyl-N-[3-(5-methoxy-1H-indol-2-yl)-1H-indazol-5-yl]benzenesulfonamide are thus obtained in the form of an amorphous cream solid (LC/MS analysis: Tr 3.52 minutes MH+=497).
