Procedure

The 3-benzoyl-10-[2-(cyclopentyloxy)phenyl]-1,2,3,4,5,6-hexahydroazepino[4,5-b]indole (0.73 g, 1.6 mmol), potassium hydroxide (2.07 g, 32.1 mmol), and ethylene glycol (15 mL) were heated to 170° C. for 2.67 hours. The reaction was diluted with water and extracted with ethyl acetate (233). The organic layers were combined, washed with brine, dried over MgSO4 and concentrated in vacuo to give a brown oil which was passed through a column of silica gel with 3% methanol/chloroform with 1% NH4OH to give 419 mg (74%) of a white foam as the title compound: 1H NMR (400 MHz, CDCl3) δ 7.83 (br s, 1 H), 7.35-7.26 (m, 3 H), 7.15-7.11 (m, 1 H), 7.03-6.96 (m, 2 H), 6.91 (d, J=7.2 Hz, 1 H), 4.69-4.65 (m, 1 H), 3.11-3.07 (m, 2 H), 2.99-2.95 (m, 2 H), 2.87-2.81 (m, 2 H), 2.45-2.39 (m, 2 H), 1.73-1.67 (m, 4 H), 1.48-1.45 (m, 4 H); HRMS (FAB) calcd for C23H26N2O+H1: 347.2123 found 321.2134.
