実験手順

5,6,7,8-Tetrahydroquinoline N-oxide (3.0 g, 19.1 mmol) was dissolved in nitroethane (30 ml), and trimethylsilyl cyanide (2.1 g, 21.0 mmol) and N,N-dimethylcarbamoyl chloride (2.1 g, 19.1 mmol) were added thereto. The reaction mixture was stirred at room temperature for 3 days, concentrated under reduced pressure, combined with saturated aqueous sodium hydrogen carbonate solution and extracted with ethyl acetate. The extract was washed with saturated brine and dried. The solvent was evaporated under reduced pressure. The residue was subjected to a silica gel column chromatography and eluted with hexane-ethyl acetate (2:1, v/v) to give the titled compound (0.52 g, 17%).
