Abstract

A procedure for the preparation of piperazine derivatives of the general formula: **(See formula)** where R1 and R2 represent a hydrogen or halogen atom and R3 represents a hydrogen atom or a phenyl group, as well as the acid addition salts thereof, the process of which is to reductively condense a compound of general formula **(See formula)** where R1 and R2 have the meaning given above, with a compound of the general formula: **(See formula)** where R3 has the meaning given above.
