2-Naphthalenecarboxaldehyde → HCID 70553191, compound

Participants

Reaction Steps

3.1 g of 2-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 one hour. The reaction mixture was cooled and the crystals then separated, which were then collected on a suction funnel. The thus obtained crude 2-naphthaldehyde 1-methyl-1-phenylhydrazone was recrystallized from ethyl acetate. The yield was 3.5 g (67.3%) of white needle-like crystals which melt at 172.5°-174.5° C.
