Reaction of primary aromatic amines (I) with malonaldehyde bis(diethyl acetal) derivatives (II, V) in ethanol gave malonaldehyde dianil derivatives (III, IV). Treatment of III with bromine afforded bromomalonaldehyde dianil (IV). III reacted with acetic anhydride to give β-(N-acetylamino)acrolein (VII) and acetylamine (VIII). Acetylation of III with acetyl chloride afforded N-acetates (VI), which reacted with acetic anhydride to give VIIb and VIIIb.
