Procedure

A mixture of tert-butyl 2-(2-nitrophenylamino)ethylcarbamate (400 mg) and palladium (10% on activated carbon, 20 mg) in ethanol (50 mL) was stirred under hydrogen (1 atm) for 5 h. The mixture was filtered through Celite and washed with methanol. The solvent was removed and the product was used in the next step without further purification.
