A suspension of 20% palladium hydroxide on charcoal (4.63 g) and N-((1R)-1-benzyl-2-(benzylamino)ethyl)-N-methylcarbamic acid tert-butylester (4.40 g, 12.4 mmol) was kept for 8 h under a hydrogen atmosphere at (pressure: 1 atm). The reaction mixture was flushed with nitrogen and filtered through a plug of celite. The solvent was removed. The crude product was purified by flash chromatography on silica (110 g), using dichloromethane/methanol/25% aqueous ammonia as eluent, to give 830 mg of N-((1R)-1-aminomethyl-2-phenylethyl)-N-methylcarbamic acid tert-butylester.
