実験手順
A mixture of [1-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl]-4-(2-pyridyl)-3-pyrrolyl]methanol (2.01 g), activated manganese dioxide (5.09 g), and tetrahydrofuran (50 ml) was stirred at room temperature overnight. After the manganese dioxide was removed by filtration, the filtrate was concentrated. The residue was subjected to silica gel column chromatography, and 1-[4-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyl]-4-(2-pyridyl)pyrrole-3-carbaldehyde (1.71 g, yield: 85%) was obtained as an oily substance from the fraction eluted with ethyl acetate-hexane (1:2, volume ratio).
