Reaction Steps

Ethyl iodide (0.6 mmol, 0.05 mL) was added to a solution of 3-{4-[3-(biphenyl-4-yloxy)-propoxy]-2-chloro-phenyl}-2-hydroxy-propionic acid (Step A) and Ag2O (0.09 mmol, 21 mg) in DMF (0.5 mL). The mixture was heated at 50° C. for 24 hours. The mixture was warmed to room temperature, and 1N HCl was added until pH 3. The aqueous phase was extracted with ethyl acetate (3×10 mL). The combined organic layers were dried (Na2SO4), filtered and evaporated. The crude was purified by chromatography on silica gel (CH2Cl2) to afford the title compound. 1H-NMR (CDCl3, 300.15 MHz): δ 7.56–7.51 (m, 4H), 7.44–7.39 (m, 2H), 7.30 (t, 1H, J=7.3), 7.20 (d, 1H, J=8.5), 6.99 (d, 2H, J=8.7), 6.95 (d, 1H, J=2.4), 6.77 (dd, 1H, J=8.5, 2.4), 4.21–4.13 (m, 5H), 3.64–3.54 (m, 1H), 3.44–3.34 (m, 1H), 3.29 (dd, 1H, J=14.1, 4.2), 3.01 (dd, 1H, J=14.1, 8.7), 2.28 (qn, 2H, J=6.0), 1.12 (t, 3H, J=6.9).
