Reaktionsschritte
[(R)-1-((R)-2-Hydroxy-propyl)-pyrrolidin-3-yl]-carbamic acid tert-butyl ester (244 mg) was prepared from [(R)-1-((R)-2-hydroxy-propionyl)-pyrrolidin-3-yl]carbamic acid tert-butyl ester (500 mg) and 1 M borane in THF (6 mL). The reaction was stirred at room temperature for 30 min and then stirred at 50° C. for 8 h. The reaction was added to methanol (20 mL). The solvent was evaporated and crude compound was purified by flash chromatography using DCM:methanol gradient.
