실험 절차

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 under ice-cooling. The mixture was stirred at room temperature for 30 min. To the reaction mixture was again added 2-methoxyethyl chloride (2.3 ml) under ice-cooling, and the mixture was stirred at room temperature for 1 hr and at 70° C. for 1 hr. After cooling, 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 an oily title compound (2.8 g).
