A solution of hydrazine hydrate (1.7 mL, 35.1 mmol) in methanol (12 mL) was added drop wise to a solution of 4-chloro-2-nitro-1-(propan-2-yl)benzene (1.75 g, 8.8 mmol) in methanol (40 mL), in the presence of iron (III) chloride (146 mg, 0.9 mmol) and activated charcoal (146 mg) and the reaction mixture was stirred under reflux for 7 h. The solid was filtered over celite, the filtrate concentrated and purified by flash chromatography (hexane/EtOAc 9/1) to obtain the title compound as a light-pink oil (1.4 g, 94%).
