実験手順

A mixture of 3-[4-(4-acetyl-3-hydroxy-2-iodo-phenoxymethyl)-benzyl]-benzoic acid methyl ester (417 mg, 0.808 mmol), 2-tributylstannanyl-pyridine (1.72 g, 4.67 mmol), and tetrakis(triphenylphosphine)palladium(0) (111 mg, 0.096 mmol) in toluene (19 mL) is thoroughly degassed, placed under nitrogen and heated at 100° C. for 16 hours. After cooling to room temperature, the reaction mixture is concentrated in vacuo. The residue thus obtained is purified by flash chromatography (20% to 40% ethylacetate in hexanes) to give 230 mg of the title compound as a yellow oil: MS (m/z): 468 (M+1); 1H NMR (CDCl3) δ 8.74 (m, 1H), 7.87 (m, 2H), 7.78 (m, 2H), 7.56 (d, J=8.0 Hz, 1H), 7.36-7.27 (m, 3H), 7.17 (d, J=8.0 Hz, 2H), 7.11 (d, J=8.0 Hz, 2H), 6.60 (d, J=9.0 Hz, 1H), 5.14 (s, 2H), 3.99 (s, 2H), 3.89 (s, 3H), 2.61 (s, 3H).
