実験手順

To a solution of 3-(3-benzyl-4-hydroxy-phenyl)-2-ethoxy-propionic acid benzyl ester (45 mg, 0.11 mol) and (5-methyl-2-phenyl-oxazol-4-yl)-acetic acid (25 mg, 0.11 mmol) in dry DCM (2.0 mL) first DMAP (2.8 mg, 0.02 mmol) and then EDCxHCl (26.5 mg, 0.13 mmol) was added and the mixture was stirred under nitrogen atmosphere at room temperature for 17 h. The solvent was removed under vacuo and the product was isolated out of the remaining oil by column chromatography using n-heptane/EtOAc (4:1) as the eluent. The title compound was obtained as an oil (56.1 mg, 82.6%). 1H NMR (400 MHz, CDCl3): δ 7.95 (m, 2H), 7.40 (m, 2H), 7.32 (m, 2H), 7.25 (m, 2H), 6.98-67.20 (m, 10H), 5.08, (d, 2H), 3.97 (t, 1H), 3.85 (s, 2H), 3.70 (s, 2H), 3.55 (m, 1H), 3.28 (m, 1H), 2.93 (d, 2H), 2.32 (s, 3H), 1.1 (t, 3H).
