Reaction Steps

To a solution of 3-methyl-6-nitroindazole (0.4 g, 2.24 mmol) in ethanol (EtOH) (10 mL) and H2O (5 mL) was added Iron (0.63 g, 11.22 mmol) and ammonium formate (1.4 g, 22.4 mmol). After heating at 90° C. for 2 h, the mixture was diluted with EtOAc, excess iron was removed by filtration, and the filtrate was washed sequentially with water, sat. NaHCO3, and brine, before it was dried and concentrated to give 6-amino-3-methylindazole (0.27 g).
