Reaction Steps

Ethylmagnesium bromide (3 M solution in diethyl ether, 77.5 mL, 233 mmol) was added to a solution of 4-bromo-benzoic acid methyl ester (20 g, 93 mmol) in tetrahydrofuran (220 mL) in a nitrogen atmosphere at 0° C., and the mixture was stirred at 0° C. for 30 minutes. The reaction mixture was then poured into a saturated aqueous ammonium chloride solution, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure to give the target compound as a colorless oil (22.1 g, 98%).
