実験手順

To a stirred solution of 1H-indol-7-ol (500 mg, 3.75 mmol) in acetone (10 mL) at r.t. was added potassium carbonate (3.11 g, 22.5 mmol), followed by iodoethane (0.45 mL, 5.63 mol), The mixture was stirred at r.t. for 16 h then solvent removed under reduced pressure. The crude product thus obtained was purified by chromatography over silica gel to afford 7-ethoxy-1H-indole: 1H NMR (400 MHz, MeOD) δ ppm 1.51 (t, J=6.95 Hz, 3 H), 4.22 (q, J=6.91 Hz, 2 H), 6.42 (d, J=3.03 Hz, 1H), 6.63 (d, J=7.58 Hz, 1 H), 6.92 (t, J=7.83 Hz, 1 H), 7.04-7.23 (m, 2 H); MS (ES+): m/z 162.20 (MH+).
