(R)-tert-butyl 3-((R)-(2-azidoethoxy)(5-chloro-2-methylphenyl)methyl)piperidine-1-carboxylate (7 g, 17.1 mmoL) was dissolved in EtOAc (300 mL), 0.8 g of Pd(OH)2 was added and the air in bottle was replaced 3 times with H2, the reaction was stirred at rt for 3 hr. The solution was filtered and concentrated to give (R)-tert-butyl 3-((R)-(2-aminoethoxy)(5-chloro-2-methylphenyl)methyl)piperidine-1-carboxylate (6.2 g), which was used in the next step without further purification.
