실험 절차

The mixture of 3-chloro-6-bromo-[1]benzothieno[2,3-c]pyridine (1.7 g, 5.8 mmol), triphenylen-2-ylboronic acid (1.6 g, 5.8 mmol), potassium phosphate tribasic (3.7 g, 17 mmol), 200 mL toluene and 10 mL water was prepared and bubbled with nitrogen for twenty minutes. Then the tris(dibenzylideneacetone)dipalladium (53 mg, 0.060 mmol) and 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (96 mg, 0.23 mmol) were added. The mixture was bubbled with nitrogen for another twenty minutes. After refluxed overnight under nitrogen, then reaction mixture was cooled to room temperature and filtered through a silica plug and washed with dichloromethane. The first several portions were discarded since they only contained impurities. The combined filtrate was concentrated to give crude product, which was recrystallized from hot dichloromethane and hexanes to give 1.8 g 3-chloro-6-(2-triphenyleneyl)-[1]Benzothieno[2,3-c]pyridine as yellow solid (4.0 mmol, 70% yield).
