Versuchsvorschrift
A mixture of {1-benzyl-3-[(4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-phenylbenzyl)oxy]-1H-pyrazol-4-yl}methanol (0.20 g), activated manganese dioxide (0.60 g) and tetrahydrofuran (10 mL) was stirred at room temperature for 5 hrs. Manganese dioxide was removed by filtration and the filtrate was concentrated. The obtained crystals were collected by filtration to give 1-benzyl-3-[(4-{[2-(2-furyl)-5-methyl-1,3-oxazol-4-yl]methoxy}-3-phenylbenzyl)oxy]-1H-pyrazole-4-carbaldehyde (0.19 g, yield 95%). Recrystallization from ethyl acetate-hexane gave colorless needle crystals. melting point: 122-123° C.
