A mixture of 2-((2-chloro-4-nitrophenoxy)methyl)pyridine (26.5 g, 0.10 mol, 1.00 equiv), iron powder (25.2 g, 0.43 mol, 4.28 equiv) and ammonium chloride (72.24 g, 1.35 mol, 13.5 equiv) in ethanol (600 ml) was stirred mechanically under refluxed for 2 hours. The reaction was allowed to cool down; the mixture of the reaction was filtered and the filtrate was taken to dryness in vacuum. The resulted solid was dissolved in methylene chloride (500 ml) and filtered. Removal of the solvent from the filtrate in vacuum gave 15.3 g of the product. MS (ESI) m/z: 235 (M+1).
