Procedure

75 g (630 ml) of 2-hydroxybenzonitrile are refluxed with 174 g (1.26 mol) of potassium carbonate and 232.2 g (1.89 mol) of ethyl bromide in 11 of acetone overnight. The solid is filtered off, the solvent is removed under reduced pressure and the residue is distilled under reduced pressure.

Workup

  1. filtrationThe solid is filtered off
  2. customthe solvent is removed under reduced pressure
  3. distillationthe residue is distilled under reduced pressure
