Reaktionsschritte
N-(N-tert-Butoxycarbonyl-3-methyl-1H-indazol-5-yl)-3-fluorobenzenesulfonamide can be obtained as described in Example 1 from 0.9 g of 5-amino-N-tert-butoxycarbonyl-3-methyl-1H-indazole, 40 ml of tetrahydrofuran, 1 ml of triethylamine and 0.78 g of 3-fluorobenzenesulfonyl chloride. 0.1 g of N-(N-tert-butoxycarbonyl-3-methyl-1H-indazol-5-yl)-3-fluorobenzenesulfonamide is thus obtained in the form of a cream solid melting at 195° C.
