実験手順

A 5-mL reaction vial equipped with a magnetic stirrer was purged with nitrogen and charged with compound 138 (220 mg, 0.33 mmol), dichlorobis(triphenylphosphine)palladium(II) (27.1 mg, 0.039 mmol), and anhydrous DMF (1 mL). Triethylamine (146 mg, 1.44 mmol) and (trimethylsilyl)acetylene (102 mg, 1.04 mmol) were added, and the reaction mixture was stirred for 10 h at 90° C. and an additional 8 h at 100° C. Evaporation of the reaction mixture to dryness followed by column chromatography purification afforded 63% yield of compound 139 as an off-white solid. 1H NMR (CD3OΔ) δ (ppm) 7.43-8.33 (m, 8H), 7.30 (d, 1H, J=6.6 Hz), 5.64 (s, 2H), 5.14 (bs, 1H), 3.68 (t, 2H, J=8.0 Hz), 2.81 (s, 3H), 1.59-1.64 (m, 3H), 0.94 (m, 2H), 0.32 (s, 9H), −0.09 (s, 9H).
