A mixture of 4-nitro-1H-indazole (760 mg, 4.68 mmol), palladium on charcoal (10%, cat.) and ethanol (30 mL) was stirred under a balloon of hydrogen for 4 hours. The reaction mixture was then filtered through celite, and the solvent removed in vacuo to yield 1H-indazol-4-ylamine (68) (631 mg, 100%).
