A second aliquot of methyl iodide (0.15 mL) was then added and the resulting mixture was stirred for 1 hour. Ethyl acetate (100 mL) and brine (100 mL) were added, the organic layer was separated, washed twice with water, dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure to give N-(3-methoxy-4-nitro-phenyl)-acetamide.
