Versuchsvorschrift

To 1,3-dibromo-2-chloro-5-methylbenzene (1000 mg, 3.52 mmol) was added NBS (688 mg, 3.87 mmol) and AIBN (57.7 mg, 0.352 mmol). The mixture was stirred at room temperature for 30 minutes and then heated to 80° C. overnight. The solution was evaporated and the residue was purified by silica gel chromatography (0-5% EtOAc/heaxnes) to provide the title compound (740 mg) as a clear oil.
