To a solution of 2-(4-{[4′-(2-ethoxyethoxy)-2′,6′-dimethylbiphenyl-3-yl]methoxy}phenyl)cyclopropanecarboxylic acid (1.27 g, 2.76 mmol) in methanol (8 mL) was added 1 M aqueous sodium hydroxide solution (2.76 mL, 2.76 mmol). An aqueous solution (2 mL) of calcium chloride (0.153 g, 1.38 mmol) was added thereto. The precipitated solid was collected by filtration, washed with water, and dried to give the title compound (1.28 g, yield 97%) as colorless crystals.
