Reaction Steps

To a solution of 2-(4-bromophenyl)acetonitrile (3.9 g) in tetrahydrofuran (50 mL) was added potassium t-butoxide (4.9 g) in an ice bath, and the mixture was stirred for 1 hr in an ice bath. 1-Bromo-2-(2-bromoethoxyl)ethane (5.8 g) was added thereto at the same temperature, and the mixture was stirred at room temperature for 10 hr. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (3.7 g).
