반응 단계

A mixture of 4-phenyl-pyrrolidin-2-one (24.2 g; 0.15 mole) and sodium hydride (80% oil suspension) (5.4 g; 0.18 mole) in tetrahydrofuran (150 ml) is refluxed for 2.5 hrs. After cooling, ethyl iodide (29 g; 0.185 mole) is added thereto, and the resulting material is refluxed for another 5 hrs. The solvent is then evaporated off; the residue is taken up into chloroform, washed with water, dried and distilled. B.p. (0.2 mm Hg)=124°-126° C. Yield: 57%.
