Procedure

To a solution of 5-(3-bromopropylidene)-5,11-dihydro-7-hydroxy-[1]benzoxepino[2,3-b]pyridine (2.59 g) in DMF (10 ml) was added 4-(4-Fluorophenyl)-4-hydroxypiperidine (1.02 g) and triethylamine (835 μM). The solution was stirred at room temperature for 23 hours. The reaction was quenched with water, extracted with ethyl acetate, and evaporated in vacuo. The residue was purified by silica gel chromatography (87:10:3 ethyl acetate: methanol:triethylamine) to yield 0.9 g (39%) of the title compound. 1H-NMR (DMSO) d: 1.64–1.69 (2H, m), 1.74–1.85 (2H, m), 2.27–2.52 (8H, m), 4.81 (1H, s), 5.16 (2H, brs), 6.08 (1H, t), 6.62–6.71 (3H, m), 7.12 (2H, t), 7.40–7.51 (3H, m), 7.72 (1H, dd), 8.48 (1H, dd), 9.09 (1H, s). ESI-MS m/z: 447 (M+1).
