実験手順
To a stirred solution of 2-bromo-5-phenoxyphenol (120 mg, 0.45 mmol) in acetone (7 mL) was added potassium carbonate (0.375 g, 2.72 mol) followed by iodoethane (0.0724 mL, 0.905 mol) at rt. The mixture was stirred at rt overnight. Reaction mixture was concentrated down in vacuo and washed with brine extracting with EtOAc. The organics were combined, dried over Na2SO4 and concentrated to afford the title compound which was used for next step without further purification. 1H NMR (400 MHz, CDCl3): δ=1.37 (t, J=6.95 Hz, 3H), 3.95 (q, J=7.07 Hz, 2H), 6.37 (dd, J=8.59, 2.78 Hz, 1H), 6.52 (d, J=2.53 Hz, 1H), 6.90-6.97 (m, 2H), 7.00-7.08 (m, 1H), 7.22-7.30 (m, 2H), 7.36 (d, J=8.59 Hz, 1H).
