Reaction Steps

A mixture of ethyl 3-[3-isopropoxy-1-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl]-1H-pyrazole-4-yl]propionate (440 mg), 1 N aqueous sodium hydroxide solution (5 ml), tetrahydrofuran (5 ml), and ethanol (5 ml) was stirred at room temperature for one hour, diluted with 1 N hydrochloric acid (5 ml), and extracted with ethyl acetate. The ethyl acetate layer was washed with saturated aqueous sodium chloride solution, dried (MgSO4), and concentrated. The obtained colorless crystals were collected by filtration, and 3-[3-isopropoxy-1-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl]-1H-pyrazol-4-yl]propionic acid was obtained (380 mg, yield: 91%). This was recrystallized from acetone-isopropyl ether. Melting point: 106–107° C.
