Reaction Steps
A mixture of ethyl 3-[1-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl]-4-phenyl-3-pyrrolyl]propionate (531 mg), lithium hydroxide monohydrate (128 mg), tetrahydrofuran (6 ml), ethanol (4 ml) and water (4 ml) was stirred at room temperature for 2 hours and acidified by adding 1N hydrochloric acid, which was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4), and then concentrated. The colorless crystals obtained were collected by filtration to yield 3-[1-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl]-4-phenyl-3-pyrrolyl]propionic acid (451 mg, yield: 90%). This was recrystallized from ethyl acetate-hexane. Melting point: 124–125° C.
