Abstract

Inventia se refera la un procedeu pentru prepararea unor derivati ai acizilor 1-etil-1,4-dihidro-4-oxo-chinolin-3-carboxilic si 1-etil-1,4-dihidro-4-oxo-1,8-naftiridin-3-carboxilic cu formula generala I: (vezi formula) în care X reprezinta un atom de carbon sau de azot si R reprezinta un atom de hidrogen sau de fluor, constând din aceea ca un compus cu formula generala II: (vezi formula) în careX si R au semnificaâiile de mai sus, se trateaza cu 2,5-dimetil oxitetrahidrofuran, în mediu de acid acetic, eventual în amestec cu dimetilformaldehida în proportie de 1:1, dupa care compusi transformati, daca se doreste, în saruri de metale alcaline sau alcalino-pamântoase, acceptabile fiziologic, prin procedee în sine cunoscute.The invention relates to a process for the preparation of 1-ethyl-1,4-dihydro-4-oxo-quinoline-3-carboxylic acid derivatives and 1-ethyl-1,4- naphthyridine-3-carboxylic acid of the general formula I wherein X represents a carbon or nitrogen atom and R represents a hydrogen or fluorine atom consisting of a compound of the general formula II: ) in which X and R have the above meanings are treated with 2,5-dimethyl oxytetrahydrofuran in acetic acid medium, optionally in admixture with dimethylformaldehyde in a ratio of 1: 1, after which the compounds are converted, if desired, into salts of alkaline or alkaline earth metals, physiologically acceptable, by processes known per se.
