実験手順
1.0 g (0.0038 mole) of 2-cyano-1-[4-(hydroxymethyl)phenyl]indole was dissolved in 150 ml tetrahydrofuran, 10.0 g of activated manganese dioxide was added, and the mixture stirred at room temperature for 16 hours. The reaction was filtered and the filtrate evaporated to an oil, which was crystallized from a mixture of methyl-t-butyl ether and hexane 1:1 to give 0.63 g (0.0026 mole) of 1-(4-formylphenyl)-2-cyanoindole as an oil.
