Combine 3-propoxy-benzylamine in 50 mL of dichloromethane and add dropwise to a mixture of 3-bromophenylacetyl chloride (4.90 gm; 21.0 mmol) and triethylamine (3.60 gm; 35.9 mmol) in 250 mL of dichloromethane at 0° C. Allow the reaction to warm to room temperature and stir for 18 h. Pour the reaction into 100 mL of saturated brine, separate the layers and extract the aqueous layer with 100 mL of dichloromethane. Combine organic layers, wash with brine, dry (MgSO4), and concentrate. Purification by chromatography on silica gel with 40% EtOAc in hexanes gives the title compound.
