Versuchsvorschrift

Phenylhydrazine (0.1 mole, commercially available from Aldrich, Milwaukee, Wis.) and 9-ethyl-3-carbazolecarboxaldehyde (0.1 mole, available from Aldrich Chemical, Milwaukee, Wis.) were dissolved in 100 ml of isopropanol in 250 ml 3-neck round bottom flask equipped with a reflux condenser and a mechanical stirrer. The solution was refluxed for 2 hours. Thin layer chromatography indicated the disappearance of the starting materials. At the end of the reaction, the mixture was cooled to room temperature. The 9-ethyl-3-carbazolecarbaldehyde phenylhydrazone crystals formed upon standing were filtered off and washed with isopropanol and dried in vacuum oven at 50° C. for 6 hours.
