実験手順

A mixture of 2-fluoro-1-(2-methoxyethoxy)-4-nitrobenzene (12.0 g , 55.7 mmol), iron powder (10.3 g, 180 mmol) and ammonium chloride (14.5 g , 270 mmol) in 170 mL of ethanol and 50 mL of water is heated at reflux for 1.5 hours then filtered hot through a pad of Diatomaceous earth, washing with ethanol. The filtrate is cooled to room temperature and the precipitated solids are removed by filtration. The filtrate is concentrated to a small volume and partitioned between ethyl acetate and water. The organic layer is dried over magnesium sulfate, filtered and concentrated in vacuo to provide 9.45 g of 3-fluoro-4-(2-methoxyethoxy)aniline as a brown liquid.
