实验步骤: To a round bottom flask with 2-mercaptobenzoxazole (2.14 g, 14.2 mmol) andDMF (100 mL) at room temperature was added K2CO3 (2.61 g, 18.9 mmol) followed by N-(8-bromooctyl)phthalimide (4.00 g, 11.8 mmol). The resulting solution was heated to 60° C. for 0.5 h and then cooled back to room temperature. At this point, the reaction mixture was quenched with H2O (100 mL) and then diluted with EtOAc (600 mL). The organic layer was washed with 1 N HCl (60 mL), sat. aq. NaHCO3 (60 mL), and brine (60 mL) and then dried (MgSO4). After concentration, the residue was purified by the Biotage Flash 40 apparatus (10 to 20% EtOAc/petroleum ether gradient) to afford the thioether intermediate. cooled back to room temperature At this point, the reaction mixture was quenched with H2O (100 mL) diluted with EtOAc (600 mL) The organic layer was washed with 1 N HCl (60 mL), sat. aq.
