Procedure

To a solution of compound NaH (416.2 mg, 17.34 mmol) in DMF (10 mL) was added 3-bromophenol (1.0 g, 5.78 mmol) at 20° C. After addition the solution was stirred for 5 minutes at this temperature before the addition of 2-(bromomethyl)oxirane (1.2 g, 8.67 mmol). The reaction mixture was stirred for 16 h at 20° C. Once complete the reaction mixture was treated with water (50 mL) and extracted with EA (2×20 mL) and the organic layers combined and washed with NaHCO3, brine (30 mL), dried over Na2SO4 and concentrated to give the compound 2-((3-bromophenoxy)methyl)oxirane (1.5 g, crude) as colorless oil which was used in next step without further purification.
