실험 절차
To 70 ml of acetonitrile were added 6 g of 4-trifluoromethylpyridine=N-oxide, 10.26 ml of triethylamine, and 10.95 g of trimethylsilyl cyanide, and the mixture was stirred at 90° C. for 20 hours. Thereafter, the reaction solution was allowed to cool to room temperature, and concentrated. The residue was subjected to silica gel column chromatography to obtain 4.5 g of 4-trifluoromethylpyridine-2-carbonitrile.
