실험 절차

To a suspension of NaH (2.2 g, 54 mmole) in THF (200 mL) was added diethyl 2-(phenylmethyl)butanedioate (12.5 g, 49.9 mmole). After 30 min at RT, bromomethyl phthalimide was added to the reaction mixture and the contents were stirred for 14 h at RT. The reaction was quenched with H2O (15 mL), diluted with Et2O (300 mL) and layers separated. The organic layer was concentrated under vacuum and the resulting residue recrystallized from EtOH)(0°) to give the title compound (13 g, 64%) as a white solid: LCMS (ES) m/z 410 (M+H)+.
