Abstract

A procedure for preparing new piperazine derivatives of the formula **(See formula)** in which R1 is a hydrogen atom, an alcohol group having 1 to 4 carbon atoms, a hydroxyalkyl group having 2 to 4 carbon atoms, a benzyl group, a methoxy-substituted benzyl group, a phenyl group, a propargyl group or an acyl group; and R3 is a hydrogen atom or an alcohol group having 1 to 6 carbon atoms; and its salts; which comprises heating a compound of the formula **(See formula)** where R1 and R3 are as defined above, and Y and Z are different from each other and each represents a hydrogen atom, a halogen atom, a lower alkoxy group, a benzyloxy group, a hydroxyl group alcoholic or its derivative, or a group that can form a tertiary or quaternary amine together with the rest, provided that either Y or Z is always a hydrogen atom; and optionally transforming the thus obtained compound of formula I into an acid addition salt or an alkaline salt by reacting it with a suitable acid or alkali.
