Versuchsvorschrift

{(1S,2R)-1-Benzyl-3-[(4-cyano-2,2-dimethyl-butyl)-(4-benzyloxybenzenesulfonyl)-amino]-2-hydroxy-propyl]-carbamic acid[1,3]dioxan-5-yl ester (2.2 mg, 0.003 mmol) was dissolved in methanol (1 mL). Solution was degassed with nitrogen for 5 minutes the 10% Pd/C (2 mg) was added. Reaction was pressurized with H2 (1 ATM) and stirred for 30 minutes. Catalyst removed by filtration and solvent was removed in vacuo leaving 2.0 mg (95%) of product as a colorless residue. MS(ES): 576.2 (M+1), HPLC; tR=10.39 min. (84%).
