To a solution of 1-chloro-2-iodo-5-methoxy-4-nitrobenzene (113 g, 0.361 mol) in acetic acid (1 L) and water (50 mL) at 50° C., Fe (50.5 g, 0.903 mol) was added and the resulting mixture was stirred at 50° C. for 2 h. The mixture was allowed to cool to room temperature and then poured into ice-water. The precipitate was collected by filtration and rinsed with water. This crude product was dissolved with ethyl acetate (1 L) and filtered. The filtrate was washed with saturated NaHCO3 solution and brine. The organic layer was dried over MgSO4, filtered, and concentrated in vacuo to afford the desired product (87 g, 85% yield).
