  4. 4
    OtherThe crude product is crystallised from heptane at reduced temperature

Procedure

210.0 g (1.10 mol) of 4-bromo-2-fluorophenol are dissolved in 1.1 l of ethyl methyl ketone, and 175.0 g (1.27 mol) of potassium carbonate and 150.0 ml (1.26 mol) of benzyl bromide are added. The mixture is refluxed for 5 h and stirred at room temperature for 16 h. The batch is filtered, and the filtrate is concentrated to dryness. The crude product is crystallised from heptane at reduced temperature.
