To a cold (−78° C.), stirred solution of (E)-1-methoxy-4-(2-nitrovinyl)benzene (153 mg, 0.86 mmol) in THF (20 mL) was added PhLi (0.64 mL, 1.6M) under Ar. After 1.5 h, the reaction was treated with MeOH, sat. NH4Cl and brine, and allowed to warm to room temperature. The reaction was extracted with EtOAc (3×), dried (MgSO4), filtered, concentrated then purified on Biotage Horizon to provide the product (150 mg, 68%) as an oil: 1H NMR (400 MHz, CDCl3) δ ppm: 7.32 (2H, t, J=7.20 Hz), 7.19-7.25 (3H, m), 7.14 (2H, d, J=8.84 Hz), 6.84 (2H, d, J=8.84 Hz), 4.90-4.96 (2H, m), 4.81-4.87 (1H, m), 3.77 (3H, s).
