Reaction Steps

N-(N-tert-Butoxycarbonyl-3-methyl-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide can be obtained as described in Example 1 from 0.9 g of 5-amino-N-tert-butoxycarbonyl-3-methyl-1H-indazole, 55 ml of tetrahydrofuran, 1 ml of triethylamine and 1.02 g of 2-methylsulfonylbenzenesulfonyl chloride. 1.5 g of N-(N-tert-butoxycarbonyl-3-methyl-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide are thus obtained in the form of a pink solid melting at 228° C.
