Versuchsvorschrift
5-Amino-3-methylamino-1H-indazole can be obtained as described in Example 4 from 0.5 g of 3-methylamino-5-nitro-1H-indazole, 25 ml of ethanol, 5.2 g of ferrous sulfate, 8 ml of water and 6.2 ml of 32% aqueous ammonia. 0.1 g of 5-amino-3-methylamino-1H-indazole is thus obtained in the form of a cream powder melting at 215° C.
