Procedure

To 3-bromophenol (2.23 g, 12.9 mmol) in DMF (100 mL) was added, in small portions, sodium hydride (60% dispersion, 0.54 g, 13 mmol) over 30 min. 1-Bromo-3-chloropropane (2.1 g, 13 mmol) was then added dropwise and the mixture was stirred at r.t. for 24 h. It was then partitioned between ether and water, the organic phase was washed with water and brine, dried (anhydrous MgSO4) and concentrated to afford 1-bromo-3-(3-chloropropoxy)benzene (362, 2.95 g, 91% yield) (used as is with no additional purification).
