The present invention relates to the field of chemical-pharmaceutical industry and medicine. An agent, exhibiting the properties of a cognitive function promoter, was selected from 1,3-dimethyl-5-[(4-pyridylamino)methylene]barbituric acid and 4-amino-1-(3-nitro-2-oxo-1-pheny-1,2-dihydro-1,6-naphthyridin-5-yl)pyridinium chloride. The compounds, that are proposed as agents, exhibit potent biological activity.

the action of various CH acids. A new approach to the synthesis of 4-(4-fluoroanilino)-5-formyl-2-oxo-1,2-dihydropyridine-3-carbonitrile using dimethylformamide diisopropylacetal under mild conditions was developed. The comparative reactivity of the formyl group in the reactions of 4-arylamino-5-formyl-2-oxo-1,2-dihydropyridine-3-carbonitriles and in 4-arylamino-2-oxo-1,2-dihydropyridine-3-carb-aldehydes
