A 100 mL 3 -neck flask was placed under N2 and equipped with a condenser and an addition funnel. Magnesium (2.0 g, 83 mmol) were added, bromo-3-chloro- 5-fluoro benzene (15 g, 72.5 mmol) was taken up in dry THF (70 mL), and transferred to the addition funnel. The Grignard reaction was initiated with approximately 2 mL of the bromo-3-chloro -5-fluorobenzene solution and iodine. The remaining bromo-3-chloro-5-fluorobenzene solution was added and the reaction was refluxed 1 hour.
