Reaction Steps
Sodium methoxide (4.5M solution in methanol, 8.80 ml, 41.0 mmol) was added dropwise to a stirred solution of 3,5-dibromofluorobenzene (5.00 g, 19.0 mmol) in N,N-dimethylformamide (95 ml) at 0° C. under a nitrogen atmosphere. The reaction was warmed to room temperature, stirred for 1 hour and then evaporated under reduced pressure. The residue was dissolved in diethyl ether and was washed with water (3×300 ml) and brine (300 ml), dried over magnesium sulphate, filtered and concentrated under reduced pressure to give the title compound as a white solid (5.13 g).
