The title compound was synthesized by two related methods. 2-Pyrrolidone (I) was alkylated with 1-bromo-3-chloropropane (II) using either sodium or potassium metal or potassium tert-butoxide as the base. The resultant N-(3-chloropropyl)pyrrolidone (III) was then condensed with 1-(4-fluorophenyl)piperazine (IV) in the presence of NaI and Na2CO3 to produce the desired disubstituted piperazine. Alternatively, the title compound was prepared from the known N-(3-chloropropyl)-N'-(4-fluorophenyl)piperazine (V) by condensation with 2-pyrrolidone (I) in the presence of sodium metal in hot xylene.
