Versuchsvorschrift

50.2 g (0.35 mol) of 2,4-difluorobenzylamine and 37.1 g (0.35 mol) of benzaldehyde are dissolved in 140 ml of toluene and heated to reflux. The water produced is separated off using a water separator. The reaction is complete (GC check) after two hours. The solution is evaporated on a vacuum rotary evaporator. 78.9 g (97% of theory) of a slightly yellow liquid are obtained.
