Abstract

Preparation process for derivatives of the pyridine of formula I and its acid addition salts **(See formula)** in which R1 is a member selected from the group consisting of a hydrogen atom and a methyl group, R2 is a member selected from the group consisting of a hydrogen atom, an alkali metal atom, an alkyl group containing from 1 to 3 carbon atoms, an alkyl group substituted with a hydroxyl group and containing from 1 to 3 atoms of carbon, a benzyl group and a benzyl group substituted with a halogen atom, and A is a member selected from the group consisting of groups - (CH2) n-, where n represents an integer greater than 1-1 and less than +2, characterized in that in order to obtain said new pyridine derivatives a pyridine derivative of general formula II is reacted: **(See formula)** wherein R1 and A have the same meanings as above and R3 is a member selected from the group consisting of halogen atom, hydroxyl group, amino group, and straight and branched chain alkoxy groups containing 1 to 4 carbon atoms, with a piperazine derivative of general formula III: **(See formula)** where R2 has the same meanings as above.
