実験手順

A mixture of [1-[4-(2-phenyl-4-oxazolylmethoxy)benzyl]-3-(2-thienyl)-1H-pyrazol-4-yl]methanol (2.03 g), activated manganese dioxide (6.00 g), and tetrahydrofuran (50 ml) was stirred at room temperature overnight. After the manganese dioxide was removed by filtration, the filtrate was concentrated to obtain 1-[4-(2-phenyl-4-oxazolylmethoxy)benzyl]-3-(2-thienyl)-1H-pyrazole-4-carbaldehyde (1.74 g, yield: 86%) as colorless crystals. This was recrystallized from ethyl acetate-hexane. Melting point: 153˜154° C.
