Procedure

To a mixture of ethyl {4-[4-({4-[({4-[(E)-2-(2-tert-butyl-1,3-oxazol-4-yl)ethenyl]-1-phenyl-1H-pyrazol-3-yl}oxy)methyl]-2-methoxyphenoxy}methyl)-5-methyl-1,3-oxazol-2-yl]phenyl}acetate (320 mg), tetrahydrofuran (5 mL) and ethanol (5 mL) was added 1N aqueous sodium hydroxide solution (1.5 mL), and the mixture was stirred at 50° C. for 1 hr. 1N Hydrochloric acid was added to the reaction mixture for neutralization, and the mixture was extracted with ethyl acetate. The residue was recrystallized from ethyl acetate-hexane and the precipitated crystals were collected by filtration to give {4-[4-({4-[({4-[(E)-2-(2-tert-butyl-1,3-oxazol-4-yl)ethenyl]-1-phenyl-1H-pyrazol-3-yl}oxy)methyl]-2-methoxyphenoxy}methyl)-5-methyl-1,3-oxazol-2-yl]phenyl}acetic acid (181 mg, yield 59%) as colorless prism crystals. melting point: 104-106° C.
