(R)-tert-butyl 3-((R)-(3-chlorophenyl)(2-(methylsulfonyloxy)ethoxy)methyl)piperidine-1-carboxylate (15 g, 34 mmol) was dissolved into anhydrous DMF (150 mL), solid NaN3 (6.7 g, 102 mmol, 3 eq) was added and the reaction mixture was heated to 80° C. for overnight. The reaction mixture was cooled to rt and then was added with EtOAc (500 mL), the organic phase was washed with water (3×100 mL) and brine (2×80 mL), dried over Na2SO4 and concentrated in vacuo to provide crude (R)-tert-butyl 3-((R)-(2-azidoethoxy)(3-chlorophenyl)methyl)piperidine-1-carboxylate (13.3 g), which was used for next step without purification.
