실험 절차

Ethyl vanillin (21.6 g, 0.130 mol) and allyl bromide (19.9 g, 0.160 mol) were heated under reflux together with potassium carbonate (27.3 g, 0.200 mol) in 150 ml acetone (abs.) for 8 hours. After cooling, the solid was filtered off and washed with acetone. A yellow oil was obtained after a thorough concentration of the organic phases.
