反応手順
5-Amino-3-phenyl-1H-indazole can be obtained as described in Example 4 from 5 g of 5-nitro-3-phenyl-1H-indazole, 75 ml of ethanol, 77.5 g of ferrous sulfate, 65 ml of water and 50 ml of 32% aqueous ammonia. 2.1 g of 5-amino-3-phenyl-1H-indazole are thus obtained in the form of a white powder melting at 62° C.
