Reaction Steps

4-Ethylphenylamine (1.00 g, 7.52 mmol, 1 equiv) was dissolved in chloroform (40 mL) and placed into an ice bath. NBS (1.34 g, 1 equiv) was then added into the solution in small portions. The mixture was warmed to room temperature and stirred for 2 hours. EtOAc (˜200 mL) was added and the mixture was filtered. The filtrate was washed with saturated aqueous K2CO3 (200 mL), saturated aqueous NaHCO3 (200 mL), and brine (200 mL), dried over magnesium sulfate and concentrated. The residue was purified by silica gel flash column chromatography using 5% to 20% EtOAc in hexanes to afford the title compound as light brown oil (1 g). MS (ES) m/z 200.0 (M+H+).
