2-Methylcinnamic aldehyde → HCID 85999068, compound

Participants

Reaction Steps

2.9 g of α-methylcinnamaldehyde and 2.4 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 α-methylcinnamaldehyde 1-methyl-1-phenylhydrazone was recrystallized from ethanol. The yield was 3.6 g (72.0%) of light yellow scalelike crystals which melt at 111.0°-112.0° C.
