Reaction Steps

In 20 ml of toluene is suspended 0.6 g of 60% sodium hydride, whereto 3 ml of 2-oxopyrrolidine is added. Under ice-cooling, 2.7 g of 2-(4-chlorobutyrylamino)-3-(2-thenoyl)pyridine is added thereto, and the mixture is stirred at room temperature for 1 hour. The mixture is poured into water, and the solvent of the toluene layer is distilled off. The residue is recrystallized from toluene-isopropyl ether to give 2-(2-oxopyrrolidin-1-yl)-3-(2-thenoyl)pyridine, m.p. 148°-150° C.
