Procedure
Phenylhydrazine (0.1 mole, commercially available from Aldrich, Milwaukee, Wis.) and 4-(Diphenylamino) benzaldehyde (0.1 mole, available from Fluka, Buchs SG, Switzerland) were dissolved in 100 ml of isopropanol in a 250 ml 3-neck round bottom flask equipped with reflux condenser and 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 4-(diphenylamino) benzaldehyde phenylhydrazone crystals that formed upon standing were filtered off and washed with isopropanol and dried in vacuum oven at 50° C. for 6 hours.
