Versuchsvorschrift
To a THF solution of (R)-3-phenyl-3-hydroxypropanenitrile was slowly added borane THF complex at room temperature and then the resulting solution was refluxed for 2.5 h. After cooling to room temperature methanolic HCl was added to the reaction mixture. Methanol and methyl borate were removed by distillation and the reaction mixture neutralized with sodium hydroxide (5N). Extraction of the mixture with dichloromethane,followed by concentration provided the crystalline (R)-3-phenyl-3-hydroxypropylamine.
