실험 절차

20 g (0.5 mol) of sodium hydroxide were dissolved in 120 ml of water. A cold solution of 109 g (0.5 mol) of 8-acetyl-1-nitroso-1,2,3,4-tetrahydroquinoline and 53 g (0.5 mol) of benzaldehyde in 300 ml of ethanol was added at 0°-5° C. The mixture was stirred at 10° C. for 1 hour, 600 ml of methylene chloride were then added and the mixture was stirred for 1 hour at 10°-20° C. 500 ml of water were then added, the organic layer was separated, dried, and the solvent was distilled off. 153.5 g of crude 8-(3-phenyl-2-propen-1-on-1-yl)-1-nitroso-1,2,3,4-tetrahydroquinoline were obtained.
