Procedure
A mixture of 4-[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]benzoic acid (0.18 g), 1-hydroxybenzotriazole ammonia complex (0.06 g), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.08 g) and N,N-dimethylformamide (5 mL) was stirred at room temperature for 15 hrs. Water was poured into the reaction mixture, 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 diethyl (E)-2-(3-{[4-({2-[4-(carbamoyl)phenyl]-5-methyl-1,3-oxazol-4-yl}methoxy)-3-methoxybenzyl]oxy}-1-phenyl-1H-pyrazol-4-yl)ethenylphosphonate as colorless crystals (0.15 g, yield 83%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 146-148° C.
