Procedure
To a solution of (S)-3-(2-Nitro-phenylamino)-hexanoic acid ethyl ester (795 mg, 2.8 mmol) in EtOH (20 mL) was added Pd/C (10% wt on carbon) (300 mg). The solution was stirred at room temperature for 3 hours. The solution was filtered and the filtrate was concentrated. The residue (683 mg, 96%) was used in the next step of the synthesis without further purification.
