Reaction Steps
To a mixture of methyl 2-[2-[[6-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]-3-pyridyl]methoxy]phenyl]acetate (0.81 g), tetrahydrofuran (4 mL) and methanol (4 mL) was added a 1N aqueous sodium hydroxide solution (3.6 mL) and the mixture was stirred at 50° C. for 1 hr. 1N Hydrochloric acid (3.7 mL) and water were added to the reaction mixture, and the precipitated solid was collected by filtration and dried with air to give crystals (0.75 g, 97%) of 2-[2-[[6-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]-3-pyridyl]methoxy]phenyl]acetic acid. Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 123-125° C.
