Reaction Steps

[2-(4-Benzyl-piperidin-1-yl)-ethyl]-carbamic acid tert-butyl ester (1.34 g, 4.2 mmol) is dissolved in CHCl3 (3 mL) and treated with TFA (3 mL) for 2 h at 20° C. The solvent is evaporated, the residue dissolved CH2Cl2 (100 mL) and washed with 1M aqueous NaOH (2×30 mL). The organic layer is dried (Na2SO4), filtered and concentrated to provide the title compound.
