Procedure
To cooled (0° C.) fuming nitric acid (100 mL) was added slowly 2-methyl-3-nitroanisole (13.0 g, 77.8 mmol) in ten times. After the addition, the mixture was warmed to r.t. and stirred for 4 h, then poured into ice-water (500 g). The resulting mixture was extracted with EtOAc (3×500 mL). The combined organic layers were washed with water, saturated NaHCO3, brine, dried over Na2SO4, and concentrated to dryness. The residue was purified by silica column chromatography (petroleum ether/EtOAc=20:1) to obtain the pure product 1-methoxy-2-methyl-3,4-dinitrobenzene.
