Reaction Steps

The title compound was prepared by the same method as 4-{2-(2-carboxy-ethyl)-3-[6-(5-dimethylcarbamoyl-3′,4′-difluoro-biphenyl-3-yloxy)-hexyl]-phenoxy}-butyric acid starting from 4-{3-[6-(5-dimethylcarbamoyl-4′-fluoro-3′-hydroxy-biphenyl-3-yloxy)-hexyl]-2-(2-ethoxycarbonyl-ethyl)-phenoxy}-butyric acid ethyl ester (142 mg, 0.213 mmol) and 1.0 N aqueous NaOH (5 mL) in THF (5 mL) and EtOH (5 mL) to afford 4-{2-(2-carboxy-ethyl)-3-[6-(5-dimethylcarbamoyl-4′-fluoro-3′-hydroxy-biphenyl-3-yloxy)-hexyl]-phenoxy}-butyric acid (120 mg, 92%) as a white amorphous solid.
