5-substituted-4-oxo-1,4-dihydro-3-pyridinecarboxylates were synthetized by reacting 1,3,5-triazine with 4-substituted ethyl acetoacetate derivatives in ethanol, in the presence of sodium ethoxide. The l-alkyl-5-substituted-4-oxo-1,4-dihydro-3-pyridinecarboxylic acids required for the antimicrobial studies were prepared by N-alkylation (with triethyl phosphate or alkyl halides) and alkaline hydrolysis
通过使1,3,5-三嗪与4-取代的乙酰乙酸乙酯衍生物在乙醇钠存在下反应,来合成5-取代的4-氧代-1,4-二氢-3-吡啶甲酸乙酯。通过N-烷基化(用磷酸三乙酯或烷基卤化物)和吡啶酮酯的碱水解制备抗微生物研究所需的1-烷基-5-取代-4-氧代-1,4-二氢-3-吡啶羧酸。
