N-benzylsulfonyl-D-leucyl-L-proline benzyl ester (1.2 g) was dissolved in methanol (20 ml), and 10% palladium-carbon (120 mg) was added. The resulting mixture aerated with hydrogen was allowed to react at room temperature for 3 h, filtered and concentrated under reduced pressure to remove the solvent to give a white foam-like solid (981 mg, 97%), which was directly used for the next reaction.
