Procedure

The title compound was prepared from 3-{3-benzyl-4-[2-(5-methyl-2-phenyl-oxazol-4-yl)-acetoxy]-phenyl}-2-ethoxy-propionic acid benzyl ester (0.054 g, 0.09 mmol) in the same manner as described for example 1 with the difference that EtOH was used as the solvent instead of EtOAc. The crude product was purified by column chromatography using DCM/MeOH (95:5) as the eluent and the desired compound was obtained as an oil (0.019 g, 41.3%). 1H NMR (400 MHz, CDCl3): δ 7.93-7.96 (m, 2H), 7.39-7.41 (m, 3H), 7.02-7.19 (m, 8H), 3.99 (m, 1H), 3.86 (s, 2H), 3.69 (s, 2H), 3.48 (m, 1H), 3.32 (m, 1H), 3.03-3.09 (dd, 1H), 2.90-2.93 (dd, 1H), 2.29 (s, 3H), 1.04-1.07 (t, 3H).
