Versuchsvorschrift

To a solution of 1.3 g of sodium metal in 100 ml of ethanol are added 6.3 g of 3-fluorophenol and 13 g of ethyl 3-fluoro-2-bromomethylbenzoate and the mixture is refluxed with heating for 8 hours. After cooling, 300 ml of water is added and the mixture is extracted with toluene. After the extract is washed with water and a saturated saline solution and dried over magnesium sulfate, the solvent is distilled off under reduced pressure. The residue is subjected to silica-gel chromatography and eluted with toluene to give 13 g of ethyl 3-fluoro-2-[(3-fluorophenyl oxy)methyl]benzoate (oil). Mass spectrum m/z: 292(M+).
