To a solution of N-(carboxymethyl)glycine (13.31 g, 100.00 mmol) in aqueous 2N NaOH (100 mL) was added a solution of benzylchloroformate (18.77 g, 110.00 mmol) in aqueous 2N NaOH (55 mL) at 0° C. The reaction was stirred at room temperature overnight and washed with Et2O. The aqueous layer was acidified to pH 2 with aqueous 1N HCl solution and extracted four times with Et2O. The combined organic layers were dried over MgSO4, filtered, and concentrated in vacuo to afford the product as a clear oil.
