The base-catalysed reaction of 3-acetyltetramanilide (II) with benzaldehyde in refluxing ethanol gave two isomeric condensation products. This indicates that both the ring methylene group (5-position) and the methyl group in α-phenylaminoethylidene group of II have the possibility of being attacked by the benzaldehyde molecule. Ratio of their yield varied with the nature of the base, the basicity and the steric requirement. Differences in the selective catalytic action between pyridine and piperidine are discussed on the basis of the results on the catalytic H-D exchange rate of the CH bonds of II susceptible to the condensation reaction.
