Reaction Steps

To (S)-5-(hydroxymethyl)pyrrolidin-2-one (2.00 g, 17.39 mmol) dissolve in 25 mL THF was added phthalimide (2.81 g, 19.13 mmol), triphenylphosphine (5.01 g, 19.13 mmol) and diisopropylazodi-carboxylate (3.33 g, 19.13 mmol). This mixture was stirred for about 16 hr, and then diluted with 200 mL of hexanes and 2 mL of DCM, and then cool at −30° C. The product precipitated and was filtered and dried (4.11 g, 96%, white solid).
