Versuchsvorschrift
N-(1H-Indazol-5-yl)benzenesulfonamide can be obtained as described in Example 1 from 0.5 g of 5-amino-1H-indazole, 25 ml of tetrahydrofuran, 1.05 ml of triethylamine and 0.73 g of benzenesulfonyl chloride. 0.6 g of N-(1H-indazol-5-yl)benzenesulfonamide is thus obtained in the form of a cream solid melting at 179° C. (analysis C13H11N3O2S % calculated C, 57.13; H, 4.06; N, 15.37; O, 11.71; S, 11.73. % found C, 56.90; H, 4.24; N, 14.21; S, 10.67).
