4-b]pyridine was obtained by intramolecular cyclization based on the previously synthesized 2-chloro-N-(6-methyl-2-oxo-4-phenyl-1,2-dihydropyridin-3-yl)acetamide. The possibility of its use in the synthesis of previously unknown 2-aminomethyloxazolo[5,4-b]pyridine derivatives by nucleophilic substitution with various amines and a cyclic amide has been shown.
