Reaction Steps

Methyl 3-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]phenyl]propionate (600 mg, 1.64 mmol) obtained in Example 16 was added to ammonia/methanol (50 ml), and the mixture was stirred for 24 hr at room temperature. The solvent was evaporated under reduced pressure. Ethyl acetate (50 ml) and 1N aqueous sodium hydroxide solution (50 ml) were added for partition. The organic layer was washed with water (50 ml) and saturated brine (50 ml), dried over magnesium sulfate, and concentrated under reduced pressure to give the title compound (464 mg, yield 80%) as a white solid.
