3-Phenylprop-2-Enal → HCID 5130700, compound

Participants

Reaction Steps

6.6 g of cinnamaldehyde and 6.1 g of 1-methyl-1-phenylhydrazine were added to 50 ml of ethanol. To the mixture, two or three drops of 1 N hydrochloric acid were added. The mixture was heated and refluxed for about one hour. The reaction mixture was cooled and the crystals then separated, which were then collected on a suction funnel. The thus obtained crude cinnamaldehyde 1-methyl-1-phenylhydrazone was recrystallized from ethanol. The yield was 6.8 g (57.6%) of light yellow needle-like crystals which melt at 113.5°-114.5° C.
