反应详情

3.7 g of 4-methoxy-1-naphthaldehyde 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 an hour. The reaction mixture was cooled and the crystals then separated, which were then collected on a suction funnel. The thus obtained crude 4-methoxy-1-naphthaldehyde 1-methyl-1-phenylhydrazone was recrystallized from ethanol. The yield was 4.0 g (69.0%) of light yellow needle-like crystals which melt at 119.5°-120.5° C.
