Vorschrift

To a solution of 2-methyl-3-nitrophenol (15.3 g, 100 mmol) in DMF (150 mL) was added sodium hydride (60% in mineral oil, 2.6 g, 110 mmol) at 0° C. and the mixture was stirred for 30 minutes at room temperature. Methyl iodide (28.4 g, 200 mmol) was added and the mixture was heated to 80° C. for 5 hours. Water (100 mL) was added and the mixture was extracted with ethyl acetate (3 times 100 mL). The combined ethyl acetate phases were dried over sodium sulphate and concentrated under vacuum to give a residue, which was purified by column chromatography on silica gel (PE:EtOAc=5:1). Evaporation afforded the title compound as a yellow solid (14.4 g).
