실험 절차

3,9-Dimethyl-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (500 mg, 2.33 mmol) was dissolved in DMF (6 ml). A solution of sodium hydride (50%) (168 mg, 7.00 mmol) was added in portions at RT and stirred at RT for 10 min. A solution of 2-(3,4-dimethoxyphenyl)oxirane (630 mg, 3.50 mmol) in DMF (4 ml) was added dropwise for 10 min and stirred for 14 h at RT. Reaction was monitored by LCMS. The reaction mixture was quenched with ice water, extracted with ethyl acetate. The organic layer was washed with brine, dried over anhydrous sodium sulfate and evaporated under reduced pressure. The crude product was purified by column chromatography to get 50 mg of pure product. 1H NMR (CDCl3, Oxalate salt) δ (ppm): 7.40-7.30 (m, 2H), 7.10-7.00 (m, 1H), 6.90-6.80 (t, 2H), 6.80-6.60 (t, 1H), 5.00-4.80 (t, 2H), 4.30-4.20 (m, 2H), 3.95 (s, 3H), 3.80 (s, 3H), 3.00-2.90 (m, 4H), 2.80 (s, 3H), 2.75-2.70 (m, 2H), 2.35 (s, 3H).
