반응 단계

A solution of methyl[3,5-dihydroxyphenyl]acetate (2.1 g, 11.5 mmol) in acetone (100 mL) was treated with potassium carbonate (2.4 g, 17.4 mmol), potassium iodide (0.38 g, 2.31 mmol) and benzyl bromide (1.5 mL, 12.7 mmol), and the mixture was stirred at room temperature overnight. The reaction was diluted with water, and was extracted with dichloromethane (×3). Combined organic extracts were dried over sodium sulfate and evaporated in vacuo. The crude material was purified on a Biotage™ 40 M column (silica), eluting with 40% ethyl acetate/hexane, to give methyl[3-benzyloxy-5-hydroxyphenyl]acetate (1.0 g, 33%). 1H NMR (400 MHz, CDCl3): δ 7.32-7.42 (m, 5H), 6.48 (d, J=1.4 Hz, 1H), 6.38-6.39 (m, 2H), 4.99 (s, 2H), 3.69 (s, 3H), 3.53 (s, 2H).
