N-{3-[2-(4-Chlorophenyl)ethyl]-1H-indazol-5-yl}-2-methylsulfonylbenzenesulfonamide can be obtained as described in Example 75 from 465 mg of N-{3-[(E)-2-(4-chlorophenyl)vinyl]-1H-indazol-5-yl}-2-methylsulfonylbenzenesulfonamide, 47 mg of 10% palladium-on-charcoal and 8 ml of dimethylformamide. 145 mg of N-{3-[2-(4-chlorophenyl)-ethyl]-1H-indazol-5-yl}-2-methylsulfonylbenzenesulfonamide are thus obtained in the form of a white solid melting at 215° C.
