Reaction Steps

To 200 g (1.00 mol) (S)-1-(4-bromophenyl)ethylamine in 800 ml DCM are slowly added 94.5 mL (1.00 mol) acetic anhydride while cooling the mixture to 20-30° C. After that the cooling is removed and the reaction mixture is stirred at r.t. over night. Afterwards the mixture is consecutivly washed with water, sat. aq. NaHCO3 solution, water, diluted aq. citric acid solution and water once again. The org. layer is dried over MgSO4 and the solvent is removed in vacuo. The crude product is used without further purification.
