Reaction Steps

A solution of hydrazine hydrate (6.95 mL, 134.7 mmol) in MeOH (50 mL) was added dropwise to a solution of 4-chloro-1-ethyl-2-nitrobenzene (6.25 g, 33.7 mmol) in MeOH (120 mL), in the presence of iron(III) chloride (547 mg, 3.4 mmol) and activated charcoal (547 mg), and the reaction mixture was stirred under reflux for 13 h. The solids were filtered over celite, the filtrate concentrated and purified by flash chromatography (hexane:AcOEt 9:1) to obtain the title compound as a light-pink oil (5.09 g, 97%).
