実験手順
A mixture of {1-benzyl-3-[(3-ethoxy-4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}benzyl)oxy]-1H-pyrazol-4-yl}methanol (0.70 g), activated manganese dioxide (2.0 g) and tetrahydrofuran (100 mL) was stirred at room temperature for 15 hrs. Manganese dioxide was removed by filtration and the filtrate was concentrated. The obtained crystals were collected by filtration to give 1-benzyl-3-[(3-ethoxy-4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}benzyl)oxy]-1H-pyrazole-4-carbaldehyde (0.65 g, yield 90%). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 144-145° C.
