Procedure

3.2 g of 2-methoxycinnamaldehyde 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 suctional funnel. The thus obtained crude 2-methoxycinnamaldehyde 1-methyl-1-phenylhydrazone was recrystallized from ethanol. The yield was 2.6 g (49.1%) of light yellow scalelike crystals which melt at 100.5°-101.5° C.
