Reaction Steps

3-Fluoro-N-(3-methyl-1H-indazol-5-yl)benzenesulfonamide can be obtained as described in Example 6 from 1.35 g of N-(N-tert-butoxycarbonyl-3-methyl-1H-indazol-5-yl)-3-fluorobenzenesulfonamide, 13.5 ml of chloroform and 0.47 ml of iodotrimethylsilane. 0.6 g of 3-fluoro-N-(3-methyl-1H-indazol-5-yl)-benzenesulfonamide is thus obtained in the form of a white foam melting at 120° C. (analysis: C14H12FN3O2S.0.39CH2Cl2 % calculated, C, 55.07; H, 3.96; F, 6.22; N, 13.76; O, 10.48; S, 10.50. % found C, 54.99; H, 2.70; N, 13.81; S, 10.18).
