Triphenylphosphine → 2-[4-(1-azabicyclo[2.2.2]oct-3-yloxy)phenyl]-1H-indole

Under N2, the mixture of product from Example 6A (114 mg, 0.5 mmol), the product from Example 6B (157 mg, 0.5 mmol), CuI (Strem Chemicals, 14 mg, 0.075 mmol), PPh3 (Aldrich, 39 mg, 0.15 mmol) and K3PO4 (212 mg, 1 mmol) in dioxane (5 mL) was stirred at 80° C. for 20 h. After the reaction was complete, it was diluted with EtOAc (30 mL) and washed with brine (2×5 mL). The organic solution was concentrated under reduced pressure and the title compound was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3.H2O, 90:10:1, Rf. 0.30) as solid (70 mg, yield, 44%). 1H NMR (300 MHz, CD3OD) δ 1.45–1.59 (m, 1H), 1.65–1.91 (m, 2H), 2.00–2.14 (m, 1H), 2.17–2.24 (m, 1H), 2.75–3.01 (m, 5H), 3.31–3.42 (m, 1H), 4.54–4.62 (m, 1H), 6.66 (d, J=0.7 Hz, 1H), 6.93–7.00 (m, 3H), 7.01–7.08 (m, 1H), 7.35 (dq, J=8.2, 1.0 Hz, 1H), 7.48 (dq, J=7.8, 0.7 Hz, 1H), 7.71 (dt, J=8.8, 2.6 Hz, 2H) ppm. MS (DCl/NH3): m/z 319 (M+H)+.
