실험 절차

10.0 g of 4-hydroxybenzaldehyde and 8.3 g of 1,3-dibromopropane were reacted for 24 hours in 6.2 g of potassium carbonate solution in 100 ml of DMF under reflux. The reaction mixture was poured into cold distilled water to obtain a precipitate. After filtration and vacuum drying the precipitate, the resultant was recrystallized in ethanol to obtain the white product (XII-1). The product yield was 76%.
