実験手順

To a solution of 5-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)picolinaldehyde (0.265 g, 0.68 mmol) in DCM (3.38 mL) at 0° C. was added methyl 2-(triphenylphosphoranylidene)acetate (0.543 g, 1.63 mmol) and the reaction was stirred at room temperature for 18 h. Upon completion the mixture was concentrated in vacuo to afford crude material which was purified by column chromatography (SiO2, 0-25% EtOAc/heptanes) to afford (E)-methyl 3-(5-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)pyridin-2-yl)acrylate (96 mg, 0.22 mmol, 32% yield). 1H NMR (400 MHz, CDCl3) δ ppm=3.70-3.75 (m, 6H), 3.79-3.83 (m, 3 H), 6.70 (d, J=15.66 Hz, 1 H), 6.77-6.88 (m, 3 H), 7.02 (dd, J=8.59, 3.03 Hz, 1 H), 7.17 (s, 1 H), 7.18-7.22 (m, 2 H), 7.48-7.59 (m, 3 H), 8.42 (d, J=2.53 Hz, 1 H). LC/MS (m/z, MH+): 448.3.
