実験手順
To a solution of 10.0 g (40 mmol) of 2-n-undecylpyridine N-oxide and 8.10 g (80 mmol) of triethylamine dissolved in 40 ml of acetonitrile was dropwise added 15.8 g of trimethylsilylanilide while stirring at room temperature. After the dropwise addition, the mixture was refluxed for 67 hours, concentrated under a reduced pressure, followed by separation by silica gel column chromatography (ethyl acetate:hexane=1:9) to give 5.40 g of an oily product (yield 52.1%).
