실험 절차
Trifluoroacetic acid (70 mL) is added dropwise to a solution of triethylsilane (2.5 mL, 15.73 mmol, d=0.728) and 2-(2-Fluoro-phenoxy)-3-(4-{2-[1-(4-methoxy-benzyl)-3-methyl-2-oxo-imidazolidin-4-yl]-ethoxy}-phenyl)-2-methyl-propionic acid ethyl ester (4.44 g, 7.86 mmol). The reaction mixture is stirred 2 h, then concentrated in vacuo. The residue is diluted with ethyl acetate, then washed with a saturated solution of aqueous sodium carbonate, water, and brine. The organic layer is dried and concentrated to provide the title compound (3.5 g, 100%). 1H NMR (400 MHz, CDCl3): δ 7.20 (d, 2H, J=8.7 Hz), 7.06-7.01 (m, 1H), 6.97-6.87 (m, 3H), 6.79 (d, 2H, J=8.7 Hz), 5.04-4.98 (m, 1H), 4.20 (q, 2H, J=6.8 Hz), 4.02 (t, 2H, J=6.8 Hz), 3.76-3.69 (m, 1H), 3.55 (t, 1H, J=8.7 Hz), 3.26, 3.14 (ABq, 2H, J=14.5 Hz), 3.21 (t, 1H, J=8.7 Hz), 2.78 (s, 3H), 2.27-2.20 (m, 1H), 1.99-1.90 (m, 1H), 1.38 (s, 3H), 1.23 (t, 3H, J=6.8 Hz), 0.96 (t, 2H, J=7.7 Hz).
