実験手順
A solution of 2-Butoxy-3-(4-{2-[1-(3-methoxy-benzyl)-3-methyl-2-oxo-imidazolidin-4-yl]-ethoxy}-phenyl)-2-methyl-propionic acid ethyl ester and 5N NaOH (0.3 mL) in ethanol (3 mL) is refluxed under nitrogen for 1 h, cooled to ambient temperature, and concentrated in vacuo. The residue is diluted with 1N HCl, extracted, dried, concentrated, and purified by LCMS to provide the title compound. 1H NMR (400 MHz, CDCl3): δ 7.22 (t, 1H, J=8.0 Hz), 7.07 (d, 2H, J=8.5 Hz), 6.83-6.79 (m, 3H), 6.72 (d, 2H, J=8.5 Hz), 4.38, 4.30 (ABq, 2H, J=15.1 Hz), 3.95 (t, 2H, J=6.0 Hz), 3.78 (s, 3H), 3.69-3.62 (m, 1H), 3.60-3.54 (m, 1H), 3.50-3.45 (m, 1H), 3.50-3.45 (m, 1H), 3.40 (t, 1H, J=9.0 Hz), 3.03-3.00 (m, 1H), 3.01, 2.95 (ABq, 2H, J=14.6 Hz), 2.85 (s, 3H), 2.26-2.19 (m, 1H), 1.92-1.85 (m, 1H), 1.62-1.55 (m, 2H), 1.48 (s, 3H), 1.42 (m, 2H), 0.93 (t, 3H, J=7.0 Hz). MS [EI+] 499 (M+H)+, [EI−] 497 (M−H)+.
