Abstract
A procedure to prepare new piperazine derivatives of the formula **(See formula)** wherein R2 is a hydrogen atom, an alcohol group having 1 to 4 carbon atoms, an alcohol group having 2 to 4 carbon atoms substituted by hydroxyl or halogen, a vinyl group, an allyl group or a benzyl group; y is a hydrogen atom or an alcohol group having 1 to 6 carbon atoms and their salts; comprising hydrolyzing or hydrogenolysis a compound of the formula **(See formula)** wherein R2 and R3 as defined above and R1'is an acyl group, an arylsulfonyl group, a benzyl group, a vinyl group, a trityl group, or a -CH2-CH2Z group in which Z is an atom of halogen, a lower alkoxy group, a benzyloxy group, an alcoholic hydroxyl group or its derivative, or a group that can form a tertiary or quaternary amine together with the remainder; 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.
