Procedure
N-[5-(3-Fluorobenzenesulfonylamino)-1H-indazol-3-yl]benzamide can be obtained as described in Example 2 from 0.45 g of N-(5-amino-1H-indazol-3-yl)benzamide, 10 ml of pyridine and 0.35 g of 3-fluorobenzenesulfonyl chloride. 0.6 g of N-[5-(3-fluorobenzenesulfonylamino)-1H-indazol-3-yl]-benzamide is thus obtained in the form of a white solid melting at 225° C. (analysis C20H15FN4O3S, % calculated C, 58.53; H, 3.68; F, 4.63; N, 13.65; O, 11.69; S, 7.81. % found C, 58.38; H, 3.42; N, 13.56; S, 7.44).
