Reaction Steps

To 10 ml of dichloromethane are added 1.02 g of 2-amino-3-(2-thenoyl)pyridine and 0.48 ml of pyridine, whereto a solution of 1.1 g of 4-(2-oxopyrrolidin-1-yl)butyryl chloride in 5 ml of dichloromethane is added dropwise under ice-cooling. The mixture is stirred at room temperature for 2 hours. After the completion of the reaction, water is added to the reaction mixture. The dichloromethane layer is washed with water, and then the solvent is distilled off. The residue is recrystallized from a mixed solvent of ethyl acetate and ethanol to give 2-[4-(2-oxopyrrolidin-1-yl)butyrylamino]-3-(2-thenoyl)pyridine, m.p. 149°-151° C.
