Reaction Steps
10 g (30 mmol) of N-[4-(p-fluorophenyl)-2-oxopyrrolidin-1-ylacetoxy]-succinimide and 3.0 g (30 mmol) of piperazin-2-one (ketopiperazine) are stirred at room temperature in 100 ml of dimethylformamide for 16 hours. The whole is concentrated to dryness by evaporation at 70° under reduced pressure, extracted at boiling temperature with trichloromethane, allowed to cool, filtered with suction and allowed to dry in the air. 1-[4-(p-fluorophenyl)-2-oxopyrrolidin-1-ylacetyl]-3-oxopiperazine having a melting point of 200°-203° is obtained.
