Procedure

To a mixture of methyl 2-[2-[4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyloxy]-5-phenylphenyl]acetate (0.65 g), tetrahydrofuran (3 mL) and methanol (3 mL) was added a 1N aqueous sodium hydroxide solution (2.8 mL) and the mixture was stirred at 50° C. for 1.5 hrs. 1N Hydrochloric acid (3 mL) and water were added to the reaction mixture, and the precipitated solid was collected by filtration and dried with air to give crystals (0.65 g, 92%) of 2-[2-[4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyloxy]-5-phenylphenyl]acetic acid. Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 102-103° C.
