실험 절차

To a 30 mL screw cap vial, (E)-tert-butyl 3-(4-((2-(4-fluoro-2-methylphenyl)-6-methoxybenzo[b]thiophen-3-yl)oxy)phenyl)acrylate (100 mg, 0.204 mmol) was dissolved in 4M HCl in dioxane (153 μl, 0.612 mmol) and the reaction mixture was stirred for 10 min at room temperature. The reaction mixture was concentrated to dryness to afford (E)-3-(4-((2-(4-fluoro-2-methylphenyl)-6-methoxybenzo[b]thiophen-3-yl)oxy)phenyl)acrylic acid (88 mg, 0.202 mmol, 99% yield). 1H NMR (400 MHz, CD3OD) δ ppm=2.25 (s, 3H) 3.78 (s, 3H) 6.21 (d, J=15.66 Hz, 1H) 6.68-6.84 (m, 3H) 6.84-6.92 (m, 2H) 7.16-7.29 (m, 2H) 7.31-7.41 (m, 3H) 7.46 (d, J=16.17 Hz, 1H).
