Versuchsvorschrift

The intermediate 3-(2′-methoxybenzylidene)-2-pyrrolidone (5.0 g) obtained in Example 317 was dissolved in dimethylformamide (50 ml) and sodium hydride (0.99 g) was added thereto under ice-cooling. The mixture was stirred at room temperature for 30 min. Methyl iodide (1.72 ml) was added under ice-cooling and the mixture was stirred for 8 hr at room temperature. After completing of the reaction, the reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give the title compound (3.6 g).
