Reaction Steps

A solution of N4 -benzyloxycarbonyl-N1 -tert-butoxycarbonyl-2,2-difluoro-3-hydroxy-5-phenyl-1,4-pentanediamine (0.464 g, 1 mmol) in ethanol (20 mL) was stirred at room temperature in the presence of 10% Palladium on charcoal (0.020 g) under a hydrogen atmosphere for 5 hours. The hydrogen atmosphere was then replaced by a nitrogen atmosphere and the catalyst was filtered. The solvent was removed in vacuo leaving 0.030 g of the expected product (98% yield).
