Versuchsvorschrift

A mixture of (3-{[3-methoxy-4-(5-methyl-2-phenyl-1,3-oxazol-4-ylmethoxy)benzyl]oxy}-1-phenyl-1H-pyrazol5-yl)methanol (4.50 g), activated manganese dioxide (14.11 g) and tetrahydrofuran (100 mL) was stirred overnight at room temperature. Manganese dioxide was removed by filtration, and the filtrate was concentrated to give 3-{[3-methoxy-4-(5-methyl-2-phenyl-1,3-oxazol-4-ylmethoxy)benzyl]oxy}-1-phenyl-1H-pyrazole-5-carbaldehyde (4.01 g, yield 90%) as colorless crystals. The crystals were recrystallized from acetone-hexane. melting point: 119-120° C.
