Reaction Steps

{(3S)-1-[(1S,2R,4R)-4-Azido-2-(4-methylsulfanyl-benzenesulfonylmethyl)-cyclohexyl]-2-oxo-pyrrolidin-3-yl}-carbamic acid tert-butyl ester (350 mg), from the synthesis of Example 17 (analogous to 10f), was dissolved in MeOH (5 mL) prior to the addition of 5% Pd/BaSO4 (300 mg). A hydrogen balloon was added and the mixture was stirred. After stirring 1 h, the Pd/BaSO4 was filtered off and the solvent was concentrated to give {(3S)-1-[(1S,2R,4R)-4-amino-2-(4-methylsulfanyl-benzenesulfonylmethyl)-cyclohexyl]-2-oxo-pyrrolidin-3-yl}-carbamic acid tert-butyl ester (497 mg). MS found: (M−H)−=496.5.
