실험 절차

A solution of 4-(2-hydroxyethoxy)phenyl iodide (0.059 g, 0.22 mmol), and 4-(3-cyclopentyloxy-4-methoxyphenyl)-1,1-(ethylenedioxy)-4-ethynylcyclohexane (0.080 g, 0.22 nmol) in dry piperidine (1 mL) was treated with a mixture of tetrakis(triphenylphosphine)palladium (0.013 g, 0.011 mmol), cuprous iodide (0.0025 g, 0.013 mmol), and triphenylphosphine (crystal), as described above in Example 11. Purification of the crude product by chromatography (silica gel, 1 to 2% methanol in methylene chloride) followed by pumping in vacuo afforded the titled intermediate as a viscous oil. 1H-NMR (400 MHz, CDCl3) δ 7.39 (d, J=9.0 Hz, 2H), 7.24 (d, J=2.1 Hz, 1H), 7.13 (d-d, J=8.3 Hz, J=2.1 Hz, 1H), 6.85 (d, J=8.7, 2H), 6.84 (d, J=8.3 Hz, 1H), 4.81 (p, J=2.0 Hz, 1H), 4.09 (t, J=4.4 Hz, 2H), 4.00 (s, 4H), 3.97 (t, J=4.4 Hz, 2H), 3.84 (s, 3H), 2.3 to 1.5 (m, 21H with H2O).
