実験手順
2.0 g of 6-(2-fluorophenyl)-2-methylpyridine was dissolved in 250 ml of 1,4-dioxane. Selenium dioxide (2.67 g, Aldrich Gold Label) was added and the mixture was reluxed for 6 days. The solids were removed by filtration and the dioxane was evaporated. The crude 6-(2-fluorophenyl)-2-pyridinecarboxaldehyde was purified by chromatography on silica gel to afford pure 6-(2-fluorophenyl)-2-pyridinecarboxaldehyde.
