A mixture of 3-(4-fluorobenzoyl)-8-hydroxy-1,1-dimethyl-1,2,3,6-tetrahydroazepino[4,5-b]indole-5-carboxylic acid ethyl ester (85 mg, 0.2 mmol), sodium iodide (30 mg), potassium carbonate (140 mg, 1.01 mmol) and 4-(2-chloroethyl)morpholine (free base, 300 mg, 2 mmol) and acetone (8 mL) was heated at 75° C. for 24 hours. The solid was filtered off, and the filtrate was concentrated in vacuo, and the crude product was purified by reverse-phase preparative HPLC to give the title compound (11 mg); 1H-NMR (CDCl3): δ 10.51 (1H, s), 7.72 (1H, s), 7.67 (1H, d), 7.66-7.59 (2H, m), 7.15-7.10 (2H, m), 6.86 (1H, d), 6.76 (1H, dd), 4.27-4.17 (4H, m), 4.08 (2H, br s), 3.77 (4H, m), 2.88 (2H, br s), 2.65 (4H, br s), 1.59 (6H, s), 1.25 (3H, t); MS (ES): 536 (MH+).
