Abstract:
The present invention provides a process for producing 1,2-epoxy-3-amino-4-phenylbutane derivatives which comprises treating a 1-halo-2-hydroxy-3-amino-4-phenylbutane derivative with a base in an aprotic polar organic solvent or a mixed solvent composed of an aprotic polar organic solvent and water and then causing the resulting epoxide to crystallize out from a mixed solvent composed of an aprotic polar organic solvent and water.
