A mixture of [1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-3-pyridylmethyl]-4-phenyl-3-pyrrolyl]methanol (1.15 g), active manganese dioxide (2.30 g) and ethyl acetate (80 ml) was stirred at room temperature for 2 hours. After the manganese dioxide was removed by filtration, the filtrate was concentrated to obtain 1-[6-(5-methyl-2-phenyl-4-oxazolylmethoxy)-3-pyridylmethyl]-4-phenylpyrrole-3-carbaldehyde (1.06 g, yield 93%) as a colorless oily substance.
