Abstract
A process for the preparation of 4-oxo-1,8-naphthyridine-3-carboxylic acids and their salts of the general formula ** (See formula) ** wherein R1 is an ethyl radical, R2 is a methyl radical, R3 and R4 are hydrogens and wherein X is hydrogen or urotropin, essentially characterized by reacting an alpha-aminopyridine with an ester of formylmalonic acid either as such, already in the form of acetal, in the presence of a condensing agent such as sodium ethylate.
