Reaction Steps

(R)-tert-Butyl 3-((R)-(cyanomethoxy)(m-tolyl)methyl)piperidine-1-carboxylate (20 g, 0.04 mol) was dissolved in anhydrous THF (300 mL), and the solution was heated to reflux under nitrogen. A solution of BH3.Me2S (12 mL, 0.12 mol) in THF was added dropwise, and stirring was continued under reflux overnight. The resulting solution was cooled to rt and MeOH was added dropwise to quench the excess borane. After evaporation of the solution, the crude (R)-tert-butyl 3-((R)-(2-aminoethoxy)(m-tolyl)methyl)piperidine-1-carboxylate was obtained and used without further purification.
