Procedure

To a reaction flask, equipped with a Dean-Stark trap, is added 3,5-dichloroaniline (16.2 g., 0.10 mole), p-carboxybenzaldehyde (0.10 moles), p-toluenesulfonic acid monohydrate (0.2 g), and toluene (100 ml.). The reaction mixture is then warmed to reflux and the water (1.65 ml.) collected by azeotroping. The cooled reaction mixture is treated with charcoal and the filtrate reduced to vacuo to give an amber oil that crystallizes on standing to give N-(p-carboxybenzylidene)-3,5-dichloroaniline which is recrystallized from pentane.
