Reaction Steps

(R)-tert-Butyl 3-((R)-(3-chloro-4-fluorophenyl)(cyanomethoxy)methyl)piperidine-1-carboxylate (2.28 g, 6 mmol) was dissolved in anhydrous THF (50 mL), and the solution was heated to reflux under nitrogen. A solution of 10 M of BH3.Me2S (1.8 mL, 18 mmol) in THF was added dropwise and stirring was continued under reflux overnight. The resulting solution was cooled to 0° C., CH3OH was added dropwise to quench the reaction. Evaporation of the solvent led to crude (R)-tert-butyl 3-((R)-(2-aminoethoxy)(3-chloro-4-fluorophenyl)methyl)piperidine-1-carboxylate (2 g, yield 87%), which was used in the next step without further purification.
