Reaction Steps

(R)-2-(benzyloxycarbonylamino)-N-tert-butoxy-3-(4-phenoxyphenylsulfonyl)-propionamide (6.0 g) obtained from Example 17 was dissolved in ethanol (100 ml) and hydrogenated at 1 atmosphere in the presence of 10% palladium on carbon (6 g) for a period of 18 hours. The catalyst was filtered off and the solvent removed from the filtrate under reduced pressure to give (R)-2-amino-N-tert-butoxy-3-(4-phenoxyphenylsulfonyl)-propionamide as a glass.
