Solid LiOH (0.23 g, 9.58 mmol) was added to a stirred solution of (4-fluorophenyl)methyl 5-bromo-2-{[(4-fluorophenyl)methyl]oxy}benzoate (may be prepared as described in Description 86; 1 g, 1.92 mmol) in tetrahydrofuran (30 ml) and water (10 ml) in air at room temperature. The reaction mixture was stirred at 70° C. overnight. After cooling to room temperature, the solvent was removed to obtain a solid, which was dissolved in water (20 ml) and stirred in an ice-water bath. 1N HCl (aq) was added to adjust the pH to 4. The solid was filtered, and dried in vacuo to yield the title compound as a grey solid. 674 mg.
