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:
