Versuchsvorschrift

A mixture of ethyl (3-{4-[(4-chloromethyl-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}phenyl)acetate (7.20 g), 3-hydroxy-1-phenyl-1H-pyrazole-4-carbaldehyde (3.01 g), potassium carbonate (2.21 g) and N,N-dimethylformamide (100 mL) was stirred at 80° C. for 1 hr. 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. The residue was subjected to silica gel column chromatography to give ethyl (3-{4-[(4-{[(4-formyl-1-phenyl-1H-pyrazol-3-yl)oxy]methyl}-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}phenyl)acetate as colorless crystals (6.84 g, yield 73%) from a fraction eluted with ethyl acetate-hexane (3:2, v/v). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 145-146° C.
