The solvent is evaporated and the residue taken up in water, made alkali with 4.0 M aqueous sodium hydroxide solution and extracted into dichloromethane. The organic phase is dried over MgSO4 and evaporated to afford (S)-3-[3-(4-Chloro-phenoxy)-azetidin-1-yl]-1-methoxymethyl-propylamine. [MH]+ 285.20
