Reaction Steps
To a 0° C. slurry of NaH (460 mg, 11.4 mmol, 60 wt % dispersion in mineral oil) in DMF (14 mL) was added 1-cyclopropylethanol (0.79 mL, 7.41 mmol) dropwise. The cold bath was removed for 30 min before the addition of 1-bromo-4-fluorobenzene (1.00 g, 5.7 mmol). The resulting reaction mixture was heated to 100° C. for 3 h. At completion, the reaction was cooled to room temperature and concentrated. The resulting oil was diluted with water (30 mL) and extracted into EtOAc (3×30 mL). The combined organics were washed with brine (20 mL), then dried over MgSO4 and concentrated to provide 1-bromo-4-(1-cyclopropylethoxy)benzene (1.30 g, 95% yield). The resulting oil was used directly without further purification.
