To a solution of 3-[4-(4-methoxy-benzoyl)-piperidin-1-yl]-pyrrolidin-2-one (1.65 mmol, 500 mg) and chloroacetonitrile (1.65 mmol, 0.125 g) in THF (30 mL) and DMF (5 mL) was added sodium hydride (60%, 2.48 mmol, 0.099 g) and heated to 70° C. for 30 min. The reaction was allowed to cool to ambient temperature and dried under vacuum. Flash column chromatography (silica) was performed eluting with ethyl acetate to 20% MeOH/ethyl acetate and provided the title compound as an off-white residue (125 mg, 22.1% yield). Calculated MS=341.4. found MS (ESI) m/e 342.9 (M+H+); HPLC (Novapak 150×3.9 mm C18 column: mobile phase: 10-90% acetonitrile/water with 0.1% TFA, at 2 mL/min over 5 min.) retention time=2.472 min.
