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; R2 is an alcohol group having 1 to 4 carbon atoms, an alcohol group having 2 to 4 carbon atoms substituted by hydroxyl or halogen, or an allyl or benzyl group; and R3 is a hydrogen atom or an alcohol group having 1 to 6 carbon atoms; and its salts; which comprises reacting a compound of the formula **(See formula)** where R1 and R3 are as defined above; with an alcoholizing agent corresponding to R2; and optionally transforming the compound of formula I thus obtained into an acid addition salt or an alkaline salt by reacting it with a suitable acid or alkali.
