To a solution of 4-iodo-benzyl bromide (9.04 g, 30.4 mmol) in DMF (316 mL) was added phthalimide (4.47 g, 30.4 mmol) and cesium carbonate (14.86 g, 45.6 mmol). The reaction stirred at room temperature overnight under nitrogen atmosphere. The next day, the reaction mixture was quenched with water. The product precipitated from the quenched reaction mixture and was filtered off, washed with water, and collected as a white solid (9.5 g, 86% yield). 1H NMR (600 MHz, CDCl3): δ 7.84 (m, 2H), 7.71 (m, 2H), 7.63 (d, 2H, J=8.4 Hz), 7.17 (d, 2H, J=8.4 Hz), 4.77 (s, 2H). 13C NMR (150 MHz, CDCl3): δ 168.1, 138.0, 136.2, 134.3, 132.2, 130.8, 123.6, 93.7, 41.3.
