Methyl iodide → 2-Chloro-6-fluoroanisole

Methyl iodide (850 μl, 13.646 mmol) and potassium carbonate (943 mg, 6.824 mmol) were added to 2-chloro-6-fluorophenol (1.0 g, 6.824 mmol) in tetrahydrofuran (10 ml) and the mixture was stirred at room temperature for 3 hours. The reaction mixture was partitioned between diethyl ether (50 ml) and water (50 ml). The organic phase was extracted and further washed with water (2×20 ml) then dried over sodium sulphate and concentrated in vacuo to afford the title compound as a colourless liquid in 94% yield, 1.03 g.
