A mixture of p-bromophenol (2.61 g; 15.1 mmol), bromoacetonitrile (1.11 mL; 15.9 mmol), and Cs2CO3 (7.40 g; 22.7 mmol) in anhyd MeCN (25 mL) was heated at 80° C., under N2 overnight. The mixture was cooled, filtered through a pad of Celite and concentrated in vacuo. The residue was dissolved in a minimal amount of EtOAc/hexanes and filtered through a short pad of silica gel (EtOAc/hexanes eluent), affording the title compound as a colorless, waxy solid which was used without further purification. 1H NMR (400 MHz, CDCl3) δ 4.75 (s, 2H), 6.88 (m, 2H), 7.46 (m, 2H).
