Methyl iodide (5.3 g, 37.9 mmol, 5 eq) was added to a solution of 2-allyl-3-fluoro-6-nitro-phenol (1.5 g, 7.5 mmol) and potassium carbonate (2.1 g, 15.1 mmol, 2 eq) in anhydrous acetonitrile (20 ml) and the reaction mixture was heated to reflux for 6 hr. The reaction mixture was filtered and washed with acetonitrile and the filtrate was concentrated to dryness to yield 2-allyl-1-fluoro-3-methoxy-4-nitro-benzene (1.2 g, 75%). The crude compound was used in the next stage without purification.
