Procedure

A mixture of ethyl (4-{4-[(4-chloromethyl-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}phenyl)acetate (0.976 g), 4-[(E)-2-(2-isopropyl-1,3-oxazol-4-yl)ethenyl]-1-phenyl-1H-pyrazol-3-ol hydrochloride (0.83 g), potassium carbonate (0.691 g) and N,N-dimethylformamide (20 mL) was stirred at 90° C. for 1.5 hrs. Water was poured into the reaction mixture, and the mixture was extracted with ethyl acetate-tetrahydrofuran. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated. The residue was subjected to silica gel column chromatography and eluted with acetone-hexane (1:5-1:4-1:3, v/v) to give ethyl {4-[4-({4-[({4-[(E)-2-(2-isopropyl-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 (244 mg, yield 16%) as colorless crystals. Recrystallization from acetone-hexane gave colorless prism crystals. melting point: 106-108° C.
