Reaction Steps
N-[3-(1H-Benzimidazol-2-yl)-1-(2-trimethylsilanylethoxymethyl)-1H-indazol-5-yl]-2-methylsulfonylbenzenesulfonamide can be obtained as described in Example 2 from 130 mg of 3-(1H-benzimidazol-2-yl)-1-(2-trimethylsilanylethoxymethyl)-1H-indazol-5-ylamine, 5 ml of pyridine and 87 mg of 2-methylsulfonylbenzenesulfonyl chloride. 192 mg of N-[3-(1H-benzimidazol-2-yl)-1-(2-trimethylsilanylethoxymethyl)-1H-indazol-5-yl]-2-methylsulfonylbenzenesulfonamide are thus obtained in the form of an orange lac (Rf=0.53, silica gel thin layer chromatography, eluent: cyclohexane/ethyl acetate (50/50 by volume), mass analysis: Cl: m/z 598 (M+H)+.)
