N-(N-tert-Butoxycarbonyl-3-phenyl-1H-indazol-5-yl)-3-fluorobenzenesulfonamide can be obtained as described in Example 1 from 0.4 g of 5-amino-N-tert-butoxycarbonyl-3-phenyl-1H-indazole, 15 ml of tetrahydrofuran, 0.36 ml of triethylamine and 0.27 g of 3-fluorobenzenesulfonyl chloride. 0.45 g of N-(N-tert-butoxycarbonyl-3-phenyl-1H-indazol-5-yl)-3-fluorobenzenesulfonamide is thus obtained in the form of an ochre solid melting at 100° C.
