Reaction Steps

To a solution of ethyl 4-bromophenylacetate (2 g, 8.2 mmol) in DMF (20 mL) at 0° C. was added sodium hydride (60% in mineral oil; 0.72 g, 18.1 mmol), and the mixture was stirred for 10 minutes. 1,4-Dibromobutane (1.07 mL, 9.0 mmol) was added, and the reaction was stirred at room temperature for 30 minutes. Once no starting material was seen by analytical tlc, the mixture was worked up with EtOAc and aqueous 10% HCl, and the crude material was purified by silica gel chromatography to give the title compound.
