Reaktionsschritte

9.4 G. of p-n-hexylbenzaldehyde in 5 ml. of absolute pyridine are treated with 5.15 g. of malonic acid and 5 drops of piperidine. The mixture is then heated at 100° C. for 11 hours, subsequently poured on to cold aqueous hydrochloric acid and extracted with ether. The p-n-hexylcinnamic acid obtained after recrystallization of the crude product from hexane/ether has a melting point of 107°-109° C.
