Reaction Steps
To a solution of N-Boc-β-cyclohexyl-D-alanine (1.00 g, 3.69 mmol) and HOBt hydrate (0.678 g, 4.43 mmol) in DMF (10 mL), EDC (0.850 g, 4.43 mmol) was added. The mixture was stirred for 60 min. Then conc. NH4OH (1.00 mL, ˜14.0 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-cyclohexyl-1-oxopropan-2-ylcarbamate as a white solid (0.917 g).
