Versuchsvorschrift

The mixture of p-toluidine (10 g) and 2-nitrobenzaldehyde (14.1 g) in anhydrous ethanol was heated to reflux for 3 h. The reaction mixture was cooled to room temperature. The solvent was removed under reduced pressure. The residue was washed with diethyl ether and petro ether to give 4-methyl-N-(2-nitrobenzylidene)aniline as yellow solid (17.3 g, yield 77.2%). LC/MS m/e obsd. (ESI+) [(M+H)+] 241.2.
