반응 단계
To a solution of N-Boc-O-benzyl-D-serine (510 mg, 1.72 mmol) and HOBt hydrate (317 mg, 2.07 mmol) in DMF (9 mL), EDC (432 mg, 2.25 mmol) was added. The mixture was stirred for 60 min. Then conc. NH4OH (0.600 mL, ˜8.40 mmol) was added. It was stirred for 18 h. Water and EtOAc were added. The organic phase was separated, washed with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give (R)-tert-butyl 1-amino-3-(benzyloxy)-1-oxopropan-2-ylcarbamate (444 mg).
