Reaction Steps

A solution of diisopropylamine (6.06 mL) in THF (100 mL) was cooled to −78° C., n-butyllithium-hexane (24.9 mL, 1.6 mol/L) was added dropwise and, after the completion of the dropwise addition, the mixture was stirred at −78° C. for 1 hr. Subsequently, a solution of 4-bromo-2-fluoro-1-iodobenzene (10.0 g) in THF (50 mL) was added dropwise, and the mixture was further stirred at −78° C. for 1 hr. Methyl iodide (2.90 mL) was added dropwise at −78° C. and the mixture was further stirred at −78° C. for 2 hr, and the mixture was warmed to room temperature. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to give the title compound as a brown oil (yield: 10.5 g, yield: 100%).
