Abstract
Procedure for preparing 1,8-naphthyridine derivatives of formula (I) **(See formula)** (in which it is hydrogen or C1-6 alkyl; Y is a tertiary nitrogen-containing heterocyclic aromatic ring, which ring is attached through the nitrogen atom, or a trialkylamino group; Z is an anion) characterized in that it comprises reacting a compound of formula (III) **(See formula)** (in which the N-alkyl group has 1-6 carbon atoms) with an aromatic tertiary base or a trialkylamine in the presence of a halogen.
