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 a hydrogen atom, an alcohol group having 1 to 4 carbon atoms, an alcohol group having 2 to 4 halogen-substituted carbon atoms, an allyl group, or a benzyl group; and R3 is an alcohol group having 1 to 6 carbon atoms; which comprises heating a compound of the formula **(See formula)** wherein R1, R2 and R3 are as defined above; to thereby induce intramolecular cyclization.
