Reaction Steps

At 0° C., acetic anhydride (0.59 g, 5.75 mmol) was added dropwise into a mixture of 3-(4-bromophenyl)butan-1-amine (0.57 g, 2.5 mmol), triethylamine (1.16 g, 11.5 mmol) and 4-dimethylamino-pyridine (1.0 mg, 0.008 mmol) in anhydrous dichloromethane (10 mL) the mixture was stirred at room temperature for 1.5 hours, water (20 mL) was added and extracted with dichloromethane (10 mL×3), combined and concentrated the organic layers, the residue was purified by column chromatography (silica gel, dichloromethane/Methanol=50:1) to give N-(3-(4-bromophenyl)butyl)acetamide (0.66 g, 94.4%). LRMS (M+H+) m/z: calcd for 270.17. found 270.1.
