Procedure

To a stirred solution of (R)-4-[2-(4-Benzofuran-2-yl-phenylcarbamoyl)-2-[4-(3,3-dimethyl-but-1-enyl)-phenyl-ethyl]-benzoic acid methyl ester (0.29 g, 0.52 mmol) in EtOH/THF/H2O (4:2:1) (12 mL) at rt, was added aq. 40% NaOH (2.5 ml), The reaction mixture was stirred for overnight, After completion of the reaction, the solvent was removed under reduced pressure. The crude was taken to pH=2 with 4N HCl and the resulting mixture was extracted with ethyl acetate. The organic layer was dried over MgSO4 and concentrated, the resulting compound was dried under vacuum to afford 4-[2-(4-Benzofuran-2-yl-phenylcarbamoyl)-2-[4-(3,3-dimethyl-but-1-enyl)-phenyl-ethyl]-benzoic acid as a solid (0.27 g, 98%):
