Reaction Steps

To a solution of 4-nitrobenzaldehyde (2.0 g, 0.133 mol) in acetic acid (150 mL) and water (15 mL) was added iron powder (1.48 g, 0.265 mol). The reaction was stirred overnight at room temperature. The mixture was filtered and extracted with dichloromethane (50 mL×3). Then the organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by flash column chromatography (eluting with 10% ethyl acetate in petroleum ether) to afford 1.2 g of the pure product (yield was 75%).
