  In einer Eintopfreaktion oder in zwei getrennten Stufen werden 3-Pyrazolidinone durch Umsetzung einer β-Hydroxypropionsäure der Formel worin R2 Alkyl oder Hydroxyalkyl und R3 Hydroxyalkyl ist, mit einem Phenylhydrazin der Formel worin R4 Wasserstoff, Alkyl, Alkoxy, Hydroxyl oder Halogen ist, zu einem β-Hydroxypropionsäurehydrazid und anschliessende Zyklisierung des Hydrazids hergestellt. Bei der Zyklisierung des Hydrazids und gegebenenfalls auch schon bei seiner Bildung aus Säure- und Hydrazinkomponente ist ein saurer Katalysator anwesend. Das Verfahren führt nach kurzer Reaktionszeit zu hohen Ausbeuten an 3-Pyrazolidinonen.
