Procedure

A solution of 1-(4-chlorobenzyl)-3-{(tert-butoxycarbonyl)amino}piperidine (2.55 g, 7.85 mmol) in CH3OH (25 mL) was treated with 1 N HCl-Et2O (50 mL). The reaction mixture was stirred at 25° C. for 15 h. The solvent was removed under reduced pressure to afford 3-amino-1-(4-chlorobenzyl)piperidine dihydrochloride as an amorphous solid (2.49 g, quant). The purity was determined by RPLC/MS (>95%),; ESI/MS m/e 225.2 (M++H, C12H18ClN2).
