実験手順
A 250 mL flask with stirbar was charged with 2-bromo-3-methylphenol (2.86 g, 15.3 mmol), (bromomethyl)cyclopropane (1.80 mL, 18.6 mmol) and cesium carbonate (7.46 g, 22.9 mmol) in dimethylformamide (50 mL). The mixture was stirred for 16 hours at ambient temperature and then heated at 50° C. for 3 hours. The mixture was cooled to ambient temperature and partitioned between ethyl acetate (200 mL) and saturated aqueous sodium chloride (200 mL). The organics were washed twice with saturated aqueous sodium chloride, dried over anhydrous sodium sulfate, filtered, and concentrated to provide the title compound (3.7 g, 100%).
