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.
根据先前合成的2-氯-N-(6-甲基-2-氧代-4-苯基-),通过分子内环化获得2-(氯甲基)-5-甲基-7-苯基恶唑并[5,4- b ]吡啶。1,2-二氢吡啶-3-基)乙酰胺。通过各种胺和环状酰胺的亲核取代,已经显示出其在合成先前未知的2-氨基甲基恶唑并[5,4- b ]吡啶衍生物中的用途。
