실험 절차
To a solution of 3-(4-hydroxyphenyl)-1-propanol (3 g, 19.7 mmol) in acetone (30 mL) is added potassium carbonate (4.08 g, 29.5 mmol) and methyl bromoacetate (2.8 mL, 29.3 mmol) and the reaction is heated at reflux for 15 h. The reaction mixture is allowed to cool to RT, filtered, and the solvent removed in vacuo. The residue is purified by chromatography (SiO2, EtOAc:iso-hexane, 2:3) to afford the title compound. 1H NMR (400 MHz, CDCl3) δ 7.14 (2H, d), 6.85 (2H, d), 4.64 (2H, s), 3.82 (3H, s), 3.69 (2H, t), 2.68 (2H, t), 1.82 (2H, m).
