A solution of 32.5 g (0.156 mole) of 2-(3-dimethylaminopropoxy)benzaldehyde and 14.6 g (0.157 mole) of aniline in 150 ml of toluene is refluxed for 9 hours. Water which is formed very slowly is collected in a Dean-Stark trap. The bulk of solvent is removed on a rotary evaporator and the oily residue is fractionated to give 20.0 g of product; boiling point 165°-170° C./0.2 mm of Hg.
