Reaction Steps

(3R)-tert-butyl 3-((6-fluoro-3′-methylbiphenyl-2-yl)(2-(methanesulfonyloxy)ethoxy)methyl)piperidine-1-carboxylate (1.1 g, 2 mmol) was dissolved in anhydrous DMF (15 mL), solid NaN3 (280 mg, 4 mmol) was added and the reaction mixture was heated to 80° C. for 5 h. The mixture was cooled to rt and diluted with EtOAc and water. The organic phase was separated, washed with water and dried over MgSO4. Removal of the solvent gave (3R)-tert-butyl 3-((2-azidoethoxy)(6-fluoro-3′-methylbiphenyl-2-yl)methyl)piperidine-1-carboxylate (0.89 g, yield 90%) which was used in the next step without purification.
