実験手順
To a stirring suspension of lithium aluminum hydride in dry THF at 0° C. was added a solution of (R)-3-phenyl-3-hydroxypropanenitrile in dry THF under nitrogen. The ice bath was removed and then the reaction mixture was refluxed for 2 h. Excess lithium aluminum hydride was destroyed by adding H2O and EtOAc. The white precipitate obtained was filtered and washed with MeOH. The combined filtrate was concentrated to give (R)-3-phenyl-3-hydroxypropylamine.
