Reaction Steps

A mixture of ethyl 3-[4-phenyl-1-[4-(3-thienylmethoxy)benzyl]-3-pyrrolyl]propionate (624 mg), 1N aqueous sodium hydroxide solution (3 ml), tetrahydrofuran (6 ml), and ethanol (6 ml) was stirred at room temperature for 5 hours, and 1N hydrochloric acid (3 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), and then concentrated. The colorless crystals obtained were collected by filtration to yield 3-[4-phenyl-1-[4-(3-thienylmethoxy)benzyl]-3-pyrrolyl]propionic acid (421 mg, yield: 72%). This was recrystallized from ethyl acetate-hexane. Melting point: 118–119° C.
