Versuchsvorschrift

The product of Step A, (3S)-1-Cbz-3-(N-BOC-amino)pyrrolidine, (5.26 g, 16.4 mmol) was dissolved in EtOAc (50 mL) and treated with a saturated HCl in EtOAc (15 mL). After the reaction mixture was stirred at rt for 30 min., the volatiles were removed to provide the title compound (4.11 g, 98.1%) as a colorless solid. The crude product was used without further purification.
