Versuchsvorschrift

Propionaldehyde (14.3 ml, 11.5 g, 0.20 mol) was added to a solution of 4-nitro benzaldehyde (20.0 g, 0.13 mol) in 50% aqueous ethanol (300 ml). An aqueous solution of 1M sodium hydroxide (36 ml, 0.04 mol) was then added dropwise, with stirring, at room temperature. After stirring for 1.5 h the precipitated solid was collected by filtration and recrystallised from aqueous ethanol to give 19.4 g (77%) of the product as a yellow solid, mp 112-114° C.
