Procedure

A mixture of [1-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]benzyl]-4-phenyl-3-pyrrolyl]methanol (1.45 g), activated manganese dioxide (4.0 g), and tetrahydrofuran (60 ml) was stirred at room temperature for 3 hours. After the manganese dioxide was removed by filtration, the filtrate was concentrated to obtain 1-[4-[2-[N-methyl-N-(2-pyridyl)amino]ethoxy]benzyl]-4-phenylpyrrole-3-carbaldehyde (1.40 g, yield: 97%) as an oily substance.
