Reaction Steps

A solution of (2S,3R)-(4-Cyano-2,2-dimethyl-butyl)-[3-((3R,3aS,6aR)hexahydro-furo[2,3-b]furan-3-yloxycarbonylamino)-2-hydroxy-4-phenyl-butyl]-carbamic acid benzyl ester (0.740 g, 1.28 mmol) in EtOAc at ambient temperature was treated with 10% palladium on carbon (0.075 g) and stirred under a balloon of hydrogen. After stirring 16 h the mixture was filtered and solvent was removed in vacuo to give desired product as a colorless oil.
