Procedure

To a solution of {4-[3,3-bis-(4-bromo-phenyl)-allyloxy]-3-chloro-phenyl}-acetic acid ethyl ester (example 9) (1.0 g, 1.8 mmol) in THF (8 ml) and ethanol (5 ml) was added 1N NaOH (4.0 ml) and the reaction mixture was stirred for 1 h at room temperature. The reaction mixture was concentrated in vacuo. The residue was suspended in water and 817 mg (82%) of the title compound was isolated by filtration as the sodium salt.
