Reaction Steps

N-Phenyl-5-(3-fluorobenzenesulfonylamino)-1H-indazole-3-carboxamide can be obtained as described in Example 18 from 0.45 g of 5-(3-fluorobenzenesulfonylamino)-1H-indazole-3-carboxylic acid, 11 ml of dimethylformamide, 0.56 g of 0-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate, 0.38 g of diisopropylethylamine and 0.14 g of aniline. 70 mg of N-phenyl-5-(3-fluorobenzenesulfonylamino)-1H-indazole-3-carboxamide are thus obtained in the form of a brown solid melting above 260° C. (Analysis: C20H15FN4O3S.0.73H2O % calculated C, 58.54; H, 3.68; F, 4.63; N, 13.65; O, 11.69; S, 7.81. % found C, 58.09; H, 3.18; N, 13.58; S, 7.43).
