Reaction Steps

Lithium aluminumhydride (320 mg, 8.81 mmol) was added to a solution of 5-bromoisobenzofuran-1,3-dione (1 g, 4.4 mmol) in THF at room temperature. The mixture was heated at reflux for 3 h, cooled to −30° C., and then quenched with water. The mixture was extracted with EtOAc. The organic layer was dried over MgSO4 and concentrated to afford the title compound (1.2 g). 1HNMR (400 MHz, DMSO-d6): δ 7.54 (d, 1H), 7.42 (dd, 1H), 7.33-7.31 (m, 1H), 5.23 (t, 1H), 5.15 (t, 1H), 4.51 (d, 2H), 4.45 (d, 2H).
