反応手順
N-(3-Cyano-1H-indazol-5-yl)-3-fluorobenzenesulfonamide can be obtained as described in Example 2 from 0.6 g of 5-amino-3-cyano-1H-indazole, 12 ml of pyridine and 0.73 g of 3-fluorobenzenesulfonyl chloride. 1 g of N-(3-cyano-1H-indazol-5-yl)-3-fluorobenzenesulfonamide is thus obtained in the form of a yellow solid melting at 227° C. (analysis C14H9FN4O2S % calculated C, 53.16; H, 2.87; F, 6.01; N, 17.71; O, 10.12; S, 10.14. % found C, 52.86; H, 2.63; F, 5.67; N, 16.04).
