Perhydropyrrolo[1,2-c]imidazole-1,3-dione (II) was prepared by Urech synthesis upon condensation of proline (I) with potassium cyanate, followed by acid cyclization. Subsequent alkylation of (II) with 1-bromo-4-chlorobutane (III) in the presence of NaH in DMF provided the chlorobutyl derivative (IV). This was finally coupled with aryl piperazine (V) to yield the title compound.
