This compound has unique chemical properties. The synthetic route is as follows. Product Details of 1149-24-2
General procedure: To a mixture of ethyl acetoacetate or methyl acetoacetate (1 eqv), formaldehyde (1.1 eqv) and NH4OAc (1.5 eqv) in acetic acid (3 mL) was added FeWO4 (20 mol%) at room temperature and the mixture was heated at 80 C for 2 h (monitoring by TLC) to give poly-substituted pyridine (3), to this solution isatin (1 eqv) was added and heating continued at same temperature for 3 h (monitoring by TLC). After that the reaction mixture was cooled to room temperature neutralized with sodium bicarbonate and extracted with EtOAc (2 × 10 mL). The organic layers were washed with brine, dried using sodium sulphate .Evaporation of the solvent gave the crude product which was purified by silica gel column chromatography. Elution of the column with petroleum ether-EtOAc gave the desired product.
