Reaction Steps
NaH (50%, 0.214 g, 4.5 mmol) was added to a solution of 3-benzyl-2-pyrrolidinone (Synthesis, 1996, 8, 941-948; 0.68 g, 3.9 mmol) in THF (15 ml). The solution was stirred at room temperature for 30 minutes. Ethyl bromoacetate (0.48 ml, 4.3 mmol) was added and the mixture stirred for 12 hours. The solvent was removed in vacuo and the residue purified by chromatography eluting with 50% EtOAc in hexane to give the product as a light yellow oil. NMR (90 MHz, CDCl3) 7.2 (m, 5H), 4.2 (m, 3H), 3.25 (m, 1H), 2.75 (m, 2H), 2.3-1.6 (m, 4H), 1.3 (t, 3H).
