Procedure

N-(3-Iodo-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide can be obtained as described in Example 2 from 25.7 g of 5-amino-3-iodo-1H-indazole, 440 ml of pyridine and 25.3 g of 2-(methylsulfonyl)benzenesulfonyl chloride. 39 g of N-(3-iodo-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide are thus obtained in the form of a brown solid (mass analysis: CI: m/z 478 (M+H)+, m/z 495 (M+NH4)+, m/z 260 (base peak)).
