Procedure

To a mixture of methyl 5-{4-({4-[({4-[(E)-2-(diethoxyphosphoryl)ethenyl]-1-phenyl-1H-pyrazol-3-yl}oxy)methyl]-2-methoxyphenoxy}methyl)-5-methyl-1,3-oxazol-2-yl}-2-methoxybenzoate (0.10 g), tetrahydrofuran (1 mL) and ethanol (1 mL) was added 1N aqueous sodium hydroxide solution (0.5 mL); and the mixture was stirred at 50° C. for 1 hr. To the reaction mixture were added 1N hydrochloric acid (1 mL) and water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated to give 5-{4-({4-[({4-[(E)-2-(diethoxyphosphoryl)ethenyl]-1-phenyl-1H-pyrazol-3-yl}oxy)methyl]-2-methoxyphenoxy}methyl)-5-methyl-1,3-oxazol-2-yl}-2-methoxybenzoic acid as colorless crystals (0.08 g, yield 80%). Recrystallization from acetone-hexane gave colorless prism crystals. melting point: 171-172° C.
