methods for the synthesis of biologically important pyridin-2(1H)-onederivatives have been developed. The behavior of enamine 1 with aromatic amines in an aqueous solution of HCl resulted in the formation of substituted enamines 2a–f at ambient temperature. The obtained product enamines 2a–f, upon treatment with 2,2,6-trimethyl-4H-1,3-dioxin-4-one, generated pyridin-2(1H)-onederivatives 5a–f along with
