An intimate mixture of 2.0 grams of 2-fluoro-5-nitrophenol, 2.0 grams of potassium carbonate, and 1.0 ml. of methyl sulphate, is heated on the steam bath for 5 minutes and then steam distilled, the volume of liquid in the flask being kept as small as possible. The 2-fluoro-5nitroanisole passes over, and a further quantity is obtained by adding more potassium carbonate (1 gram) and methyl sulphate (0.5 ml.) to the residual liquor, which is then warmed and steam distilled. The 2-fluoro-5-nitroanisole is then recrystallized from hexane.
