실험 절차
D-Phenylglycine (R) (85.2 mmol) was dissolved in anhydrous THF (260 mL) with NaHCO3 (256 mmol) in water (260 mL). Ethylchloroformate (0.235 mol) was added. After stirred at room temperature overnight, the reaction mixture was acidified to pH 3 with 1N HCl. The aqueous layer was extracted with EtOAc. The organic layers were dried over MgSO4, filtered, and concentrated under reduced pressure to give (R)-2-(ethoxycarbonylamino)-2-phenylacetic acid 41 as a white solid in 82% yield. MS (ESI, EI+) m/z=224.2 (MH+).
