General procedure: In a round-bottomed flask, the substrate (1 mmol) and aqueous HBr(48percent) (1 mL) were mixed in DMSO (1 mL). The mixture was stirredat corresponding temperature for 1–4 h. After cooling to roomtemperature, the reaction was adjusted to pH 7–8 with aqueous NaOHsolution (4 M). Then the mixture was washed twice with EtOAc, andthe combined organic extracts were dried, filtered and concentratedunder reduced pressure to give bromination products.
