Participants

Reaction Steps

Methyl 3-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]propionate (13.0 g, 35.6 mmol) obtained in Example 16 was dissolved in methanol (400 ml), and 1N aqueous sodium hydroxide solution (50 ml) was added with stirring at room temperature. After stirring for 15 hr, the solvent was evaporated under reduced pressure. Ethyl acetate (50 ml) and water (200 ml) were added for partition. 1N Hydrochloric acid was added to the aqueous layer to acidify same. The precipitated solid was collected by filtration, washed with water (50 ml) and dried under reduced pressure to give the title compound (12.0 g, yield 96%) as a white solid.
