The mixture is stirred at room temperature for 16 hours. The reaction mixture is diluted with EtOAc (100 mL) and is washed with H2O (50 mL×3). The organic layer is dried over sodium sulfate, concentrated and the resulting residue is purified by flash chromatography with 25% EtOAc in Hexane as the eluent to afford the desired to afford the desired 2-amino-N-[1-(4-chloro-phenyl)-ethyl]-benzamide (115 mg, 14%).
