실험 절차

35 mmol of benzyl bromide (BzBn, 35 mmol of ethyl 4-hydroxybenzoate (10), 14 g of Cs2CO3 and 40 ml of DMF were combined and stirred at RT ove night. Then the reaction mixture was poured into water and the product was collected by extraction. The organic solution was washed with brine and dried over MgSO4. After evaporation of solvent, pure product was obtained in yield of 100%.
