1-(2-Hydroxy-ethyl)-pyrrolidin-2-one (1.00 g, 7.74 mmol, commercial product), PPh3 (2.07 g, 7.90 mmol), N-hydroxy-phthalimide (1.29 g, 7.90 mmol), and diisopropyl azodicarboxylate (1.60 g, 7.90 mmol) were added to anhydrous THF at 0° C. under a nitrogen atmosphere, and the mixture was stirred. After 4 hours, the reaction mixture was purified by silica gel chromatography to give 2-(2-(2-oxo-pyrrolidin-1-yl)-ethoxy)-isoindol-1,3-dione (1.21 g).
