Versuchsvorschrift

5.0 g (30 mmol) of 4-benzylpyridine was dissolved in 30 ml of acetic acid. 3.53 ml (65 mmol) of concentrated sulfuric acid, 2.99 g (11.8 mmol) of iodine and 1.17 g (5.9 mmol) of sodium iodate were added to the solution, and the resultant mixture was stirred at 70° C. for 20 hours. After cooling, 0.15 g of sodium metaperiodate was added to the reaction mixture. After the distillation under reduced pressure, water was added to the residue, which was washed with dichloromethane. After the addition of 1 N aqueous sodium hydroxide solution followed by the extraction with dichloromethane twice, the solvent was evaporated. The residue was purified by the silica gel column chromatography to obtain the title compound.
