Reaction Steps

2,3-Dihydroisoindol-1-one (350 mg, 2.63 mmol), 1,4-bis-bromomethylbenzene (3.78 g, 14.3 mmol), Cs2CO3 (3.60 g, 11.1 mmol), in acetonitrile (20 mL), was stirred together at room temperature for 5 hours and 80° C. for 20 minutes. The reaction was partitioned between ethyl acetate and water and the organic layer was washed with brine and dried over anhydrous Na2SO4. The solvent was removed under reduced pressure and the product was purified by column chromatography (30% EtOAc/Hexanes) to afford a white solid (410 mg, 49%). 1H NMR (300 MHz, CDCl3): δ 7.92 (d, 1H), 7.49-7.55 (m, 2H), 7.37-7.42 (m, 3H), 7.28-7.31 (m, 2H), 4.82 (s, 2.03), 4.49 (s, 2H), 4.31 (s, 2H).
