실험 절차

A mixture (+/-)-3-(3-cyclopentyloxy-4-methoxyphenyl)pent-4-ynal (0.20 g, 0.73 mmol) and 1-iodo-3-(5-methyl-[1,2,4]oxadiazol-3-yl)benzene (0.21 g, 0.73 mmol) and trace tetrakistriphenylphosphine palladium (0) and trace copper(I)iodide in triethylamine (5 mL)under an argon atmosphere was heated at 80° C. for 0.25 h. The mixture was cooled to room temperature and was evaporated. The residue was purified by flash chromatography (silica gel, 35% EtOAc/Hex) to provide the title compound as a yellow oil (0.22 g, 71%).1H NMR (250 Mhz, CDCl3) δ 9.86 (t, J=1.7 Hz, 1 H), 8.15, (d, J=1.4 Hz, 1 H), 8.01 (dt, J=7.8 and 1.4 Hz, 1 H), 7.54 (dt, J=7.8 and 1.4 Hz, 1 H), 7.42 (t, J=7.8 Hz),lH), 6.95 (m. 2 H), 6.84 (d, J=8.5 Hz, 1 H), 4.8 (m, 1 H), 4.40 (t, J=7 Hz, 1 H), 3.85 (s, 3 H), 2.86-3.10 (m, 2 H), 2.66 (s, 3 H), 1.80-2.05 (m, 6 H), 1.60-1.69 (m, 2 H).
