Abstract
A process for obtaining N, N'-disubstituted piperazines of general formula (I) **(See formula)** wherein the substituents R1 and R4 represent a hydrogen atom or an alkyl group with or without additional substituents, or an aralkyl group, R2 and R3 interchangeably represent hydrogen atoms, alkyl groups with or without branches and with or without additional functional groups, or aryl radicals, or joined together, a polymethylene chain with three to eight links; in some cases R4 may also represent an alkoxycarbonyl group, characterized in that a compound having the following general formula (II) **(See formula)** in which the same significance for the substituents R1, R2 and R3 is maintained as indicated above, it is transformed into another of general formula (III) **(See formula)** in which R1, R2 and R3 maintain the above significance and X represents A halogen atom, which is finally reacted with an N-monosubstituted piperazine derivative of general formula (IV) **(See formula)** where R4 has the significance given above.
