Reaction Steps

N-[5-(2-Methylsulfonylbenzenesulfonylamino)-1H-indazol-3-yl)-acetamide can be obtained as described in Example 28 from 0.5 g of N-(3-amino-1H-indazol-5-yl)-2-methylsulfonylbenzenesulfonamide, 3 ml of pyridine and 98 μl of acetyl chloride. 338 mg of N-[5-(2-methylsulfonylbenzenesulfonylamino)-1H-indazol-3-yl)-acetamide are thus obtained in the form of a white solid which decomposes at approximately 145° C.
