Sodium borohydride → (S)-N-Benzyl-N-methyl-2-[N-(t-butoxycarbonyl)-2-hydroxy-ethylamino]-3-phenyl-propionamide

Participants

Reaction Steps

Combine (S)-N-benzyl-N-methyl-2-[N-(t-butoxycarbonyl)-2-oxo-ethylamino]-3-phenyl-propionamide (5.0 mmol) and sodium borohydride (5.0 mmol) in ethanol (20 mL). Stir for 16 hours. Concentrate in vacuo to obtain a residue. Dilute the residue with ethyl acetate and extract with 0.5M hydrochloric acid solution and water. Separate the layers, dry the organic layer over MgSO4, filter, and evaporate in vacuo to give the title compound.
