A solution of 4-nitro-1-phenyl-1H-indazole (0.140 g, 0.585 mmol), ammonium chloride (0.016 g, 0.293 mmol) in 4:1 v/v EtOH/water (5 mL) was treated with iron (0.327 g, 5.85 mmol) and refluxed for 2 hours. The mixture was concentrated and the residue taken in EtOAc/water, filtered through glass fiber filter paper and concentrated again to provide 1-phenyl-1H-indazol-4-amine (0.071 g, 58% yield) as a beige solid.
