Reaction Steps
3-Hydroxy-pyrrolidine (10 g, 115 mmol, 1.0 equiv) was dissolved in 2 N NaOH (100 mL) and the mixture was cooled to 0° C. Benzylchloroformate (21 g, 126 mmol, 1.1 equiv) was added dropwise over a 45 min period. After addition, the reaction was stirred at room temperature for 4 h at which time the pH was adjusted to 7-8 using concentrated HCl. The product was extracted with 3×100 mL of CH2Cl2. The organic extracts were combined and dried over Na2SO4, decanted and concentrated in vacuo to yield the desired product as a light yellow oil (24.1 g, 95%) that was used without further purification.
