Procedure

To a mixture of 4-[(4-chloromethyl-2-methoxyphenoxy)methyl]-2-(2-furyl)-5-methyl-1,3-oxazole (0.38 g), diethyl 2-(3-hydroxy-1-phenyl-1H-pyrazol-4-yl)ethylphosphonate (0.47 g) and N,N-dimethylformamide (20 mL) was added sodium hydride (60% in oil, 0.050 g) at room temperature. The mixture was stirred at room temperature for 6 hrs. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel column chromatography to give diethyl 2-{3-[(4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-methoxybenzyl)oxy]-1-phenyl-1H-pyrazol-4-yl}ethylphosphonate as a colorless oil (0.60 g, yield 80%) from a fraction eluted with ethyl acetate-hexane (3:1, v/v).
