Procedure

75 g (630 mmol) of 2-hydroxybenzonitrile, 174 g (1.26 mol) of potassium carbonate and 232.3 g (1.89 mol) of n-propyl bromide in 11 of acetone are refluxed 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
