Procedure

1-Bromo-5-cyclopentyl-4-methoxy-2-nitrobenzene (100 mg, 0.33 mmol) was dissolved in acetic acid (1 mL) and water (250 μL) and treated with Zn (109 mg, 1.67 mmol) at room temperature and stirred for 1.5 h. The reaction was diluted with ethyl acetate and filtered. The organic layer was washed with 50% saturated NaHCO3 and brine, dried over Na2SO4, filtered, and concentrated in vacuo to provide 2-bromo-4-cyclopentyl-5-methoxyaniline as a clear brown oil (85 mg, 94% yield). LC/MS m/z 270.2 [M+H]+.
