Reaction Steps

(R)-tert-butyl 3-((R)-(5-chloro-2-methylphenyl)(2-(methylsulfonyloxy)ethoxy)methyl)piperidine-1-carboxylate (8.4 g, 18.3 mmol) was dissolved in anhydrous DMF (150 mL), solid NaN3 (3.56 g, 54.8 mmol.) was added and the reaction mixture was heated to 60° C. for overnight. The reaction mixture was cooled to rt and diluted with EtOAc (500 mL), the organic phase was washed with water (5×50 mL) and brine (100 mL), dried over Na2SO4 and concentrated in vacuo to give (R)-tert-butyl 3-((R)-(2-azidoethoxy)(5-chloro-2-methylphenyl)methyl)piperidine-1-carboxylate (7 g).
