실험 절차

25 g (210 mmol) of 2-hydroxylbenzonitrile are heated, together with 87 g of potassium carbonate and 34.3 g (314.8 mmol) of ethyl bromide, in 500 ml of acetone under reflux overnight. The solid is filtered off, the solvent is removed in vacuo and the residue is distilled in vacuo. 30.0 g (97%) of a colorless liquid are obtained.
