Procedure

A mixture of 3-benzoyl-9-bromo-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (1.00 g, 2.71 mmol), phenol (0.51 g, 5.42 mmol), copper (I) oxide (0.019 g, 0.14 mmol), and cesium carbonate (2.65 g, 8.12 mmol) in o-xylene was refluxed for 24 h. After cooling to room temperature, the mixture was filtered and washed with ethyl acetate. The filtrate was concentrated in vacuo to dryness, and the residue was subjected to column chromatography (silica gel, 60% EtOAc/hexane) to afford 0.11 g (10%) of a colorless solid as the title compound: 1H NMR (300 MHz, CDCl3) δ 7.42, 7.29-7.19, 7.03-6.86, 4.12-3.91, 3.72-3.61, 3.20-3.04, 2.90-2.76; MS (ESI+) m/z 383 (M++1).
