1-Aryl-3-pyrrolin-2-one derivatives (6a-e) were obtained from the corresponding γ-bromoacetoacetanilide derivatives (1a-e) in the overall yields of 31 - 48% through the reduction of the β-carbonyl group, acetylation of the hydroxyl group, and subsequent cyclization and elimination to the 3-pyrrolin-2-one structure.
