실험 절차

After a mixture of ethyl 3-[3-ethoxy-1-[4-(5-phenyl-3-pyridylmethoxy)benzyl]-1H-pyrazol-4-yl]propionate (700 mg), 1N aqueous sodium hydroxide solution (3 ml), tetrahydrofuran (5 ml), and ethanol (5 ml) was stirred at room temperature for 2 hours, 1 N hydrochloric acid (3 ml) was added to the mixture, and then the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4) and concentrated. The resulting colorless crystals were collected by filtration to obtain 3-[3-ethoxy-1-[4-(5-phenyl-3-pyridylmethoxy)benzyl]-1H-pyrazol-4-yl]propionic acid (560 mg, yield: 85%). This was recrystallized from acetone-hexane. Melting point: 92–93° C.
