Versuchsvorschrift
To a solution of 3-(3-phenyl-1-propenyl)nitrobenzene (10.5 g) in 200 ml of ethanol were added 70 ml of 35% ammonia water and 44 g of sodium disulfide. After heating under reflux for 2 hours, the solvent was removed under reduced pressure, followed by extraction with ethyl acetate. The extract was washed with water and dried over magnesium sulfate. The solvent was removed by distillation under reduced pressure to give 7.8 g of 3-(3-phenyl-1-propenyl)aniline (yield, 85%). B.P. 128°-130° C./0.09 mmHg.
