Procedure

A slurry of 2-Methyl-3-(4-{2-[2-oxo-1-(4-trifluoromethyl-benzyl)-imidazolidin-4-yl]-ethoxy}-phenyl)-2-phenoxy-propionic acid ethyl ester (0.544 g, 0.953 mmol) and sodium hydride (0.042 g, 1.05 mmol, 60% dispersion on mineral oil) in DMF (10 mL) is stirred for 1 h, then cooled to 0° C. Iodomethane (0.60 mL, 9.53 mmol, d=2.28) is added, then the reaction mixture is stirred 18 h at ambient temperature and diluted with ethyl acetate. The organic layer is washed, dried, concentrated, and purified by flash chromatography to provide the title compound. 1H NMR (400 MHz, CDCl3): δ 7.56 (d, 2H, J=8.0 Hz), 7.37 (d, 2H, J=8.0 Hz), 7.26-7.19 (m, 2H), 7.15 (d, 2H, J=8.9 Hz), 6.97 (t, 1H, J=8.0 Hz), 6.82 (d, 2H, J=8.0 Hz), 6.74 (d, 2H, J=8.9 Hz), 4.46, 4.38 (ABq, 2H, J=15.1 Hz), 4.20 (q, 2H, J=7.1 Hz), 3.97 (t, 2H, J=7.1 Hz), 3.67-3.59 (m, 1H), 3.78 (t, 1H, J=8.9 Hz), 3.26, 3.10 (ABq, 2H, J=14.2 Hz), 2.99 (t, 1H, J=8.9 Hz), 2.85 (s, 3H), 2.28-2.21 (m, 1H), 1.93-1.84 (m, 1H), 1.39 (s, 3H), 1.21 (t, 3H, J=7.1 Hz). MS [EI+]. 585 (M+H)+. Rf=0.35 in 50% acetone in hexanes.
