الإجراء التجريبي

24.4 g (0.2 mol) of p-hydroxybenzaldehyde, 30 g (0.1 mol) of 1,10-dibromodecane and 11.2 g (0.2 mol) of KOH (85%) are heated under reflux in 200 ml of DMF for 30 min. The solution is then allowed to cool to room temperature and is poured into water/ice. The resulting solid is isolated by suction filtration. For purification, the product, which is still moist, is recrystallized from ethanol/water and dried at 70-80° C.
