(S)-(1-{4-[(4-Benzyloxy-phenyl)-(3-methyl-but-2-enyl)-amino]-piperidine-1-carbonyl}-3-methyl-butyl)-carbamic acid tert-butyl ester (1.07 g, 1.90 mmol) was dissolved in CH2Cl2 (4.5 mL) and treated with TFA (4.5 mL). The reaction was stirred for 25 minutes, then concentrated in vacuo. The residue was dissolved in EtOAc (175 mL) and solution was washed twice with saturated bicarbonate solution and brine, dried over Na2SO4, and concentrated in vacuo to give 0.87 g (99%) of the desired product as a pale oil.
