To a mixture of 3-(4-(4-methoxybenzoyl)piperidin-1-yl)pyrrolidin-2-one (70 mg, 0.232 mmol) and 5-(bromomethyl)-2-chlorobenzonitrile (80 mg, 0.347 mmol) in THF (1 mL) and DMF (0.1 mL) was added NaH (46.3 mg, 1.16 mmol, 60%). The reaction was concentrated in vacuo then taken up in dichlormethane and MeOH and filtered through a short plug of silica gel. The pooled fractions containing the title material were pooled, concentrated and neutralized with NaHCO3. MeOH was added and the solution was cooled in a freezer. The title compound was obtained by collecting the white solid via filtration (45 mg). HRMS calculated for C25H26ClN3O3 451.1671. found (ESI, [M+H]+) 452.1744.
