Procedure

To a solution of 2-(3,5-dimethoxy-phenyl)-ethylamine (1.01 g, 5.57 mmol) in anhydrous DMF (50 mL) is added 4-fluorophenyl acetic acid (860 mg, 5.57 mmol), PyBOP (3.17 g) and N-ethyldiisopropylamine (2.2 mL, 12.8 mmol). The mixture is stirred at rt for 14 h. Water (60 mL) is added, and the mixture is extracted with EtOAc (4×60 mL). The combined organic phases are washed with brine, dried over MgSO4, filtered and concentrated in vacuo. The residue is purified by silica gel column chromatography (EtOAc/Hex, 7:3) to afford the title compound as a yellow oil.
