실험 절차

A 15-mL three-neck round-bottomed flask equipped with a magnetic stirrer, nitrogen inlet and reflux condenser was charged with 23 (53 mg, 0.212 mmol), 11 (98 mg, 0.212 mmol), cesium carbonate (152 mg, 0.468 mmol) and 1,4-dioxane (3 mL). After bubbling nitrogen through the resulting solution for 30 minutes, Xantphos (10.4 mg, 0.018 mmol) and tris(dibenzylideneacetone)dipalladium(0) (9.70 mg, 0.010 mmol) were added and the reaction mixture was heated at reflux for 3 h. After this time the reaction was cooled to room temperature, filtered and the filter cake washed with methylene chloride (2×25 mL). The filtrate was then concentrated under reduced pressure and the residue was purified by column chromatography to afford 24 (68 mg, 52%) as a yellow solid: mp 133-134° C.; 1H NMR (500 MHz, DMSO-d6) δ 9.79 (br s, 1H), 9.19 (br s, 1H), 7.93 (d, 2H, J=8.5 Hz), 7.68 (s, 1H), 7.30 (m, 5H), 7.20 (s, 1H), 4.56 (s, 1H), 3.55 (s, 3H), 3.01 (s, 3H), 2.84 (m, 1H), 2.76 (m, 5H), 2.63 (t, 2H, J=5.5 Hz), 2.28 (s, 3H), 2.02 (s, 3H), 1.79 (m, 4H), 0.91 (m, 6H); MS (ESI+) m/z 627.5 (M+H); [α]25D+24.0° (c 0.25, chloroform).
