Versuchsvorschrift
A heterogeneous reaction mixture of 4-bromo-2-methoxy-6-nitrotoluene (500 mg, 2.032 mmol), acetic acid (20 ml), and iron (1135 mg, 20.32 mmol) was stirred at rt for 24 hr. Ethyl actetate was added, then the mixture was filtered through celite and the filtrate concentrated. The residue was partitioned between ethyl acetate and saturated aqueous sodium bicarbonate solution. The aqueous layer was extracted with further ethyl acetate. The combined organic phases were washed with water and brine, then dried over sodium sulfate, filtered and concentrated to afford the title compound. MS m/z: 218.0 (M+H)+.
