실험 절차

A mixture of ethyl 3-[1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-2-naphthylmethyl]-4-phenyl-3-pyrrolyl]propionate (304 mg), 1N aqueous sodium hydroxide solution (2 ml), tetrahydrofuran (4 ml) and ethanol (4 ml) was stirred at room temperature for 7 hours, and 1N hydrochloric acid (2 ml) was added to the mixture, which was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4), then concentrated. The colorless crystals obtained were collected by filtration to yield 3-[1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-2-naphthylmethyl]-4-phenyl-3-pyrrolyl]propionic acid (243 mg, yield: 84%). This was recrystallized from tetrahydrofuran-hexane. Melting point: 122–123° C.
