実験手順

A mixture of ethyl (4-{4-[(4-chloromethyl-2-methoxyphenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}phenyl)acetate (0.66 g), 4-{(E)-2-[5-methyl-2-(piperidin-1-yl)-1,3-thiazol-4-yl]ethenyl}-1-phenyl-1H-pyrazol-3-ol hydrochloride (0.44 g), potassium carbonate (0.30 g) and N,N-dimethylformamide (20 mL) was stirred at 90° C. for 2 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 to give ethyl [4-{4-[(2-methoxy-4-{[(4-{(E)-2-[5-methyl-2-(piperidin-1-yl)-1,3-thiazol-4-yl]ethenyl}-1-phenyl-1H-pyrazol-3-yl)oxy]methyl}phenoxy)methyl]-5-methyl-1,3-oxazol-2-yl}phenyl]acetate (0.59 g, yield 72%) as crystals. Recrystallization from ethyl acetate-hexane gave yellow prism crystals. melting point: 131-132° C.
