실험 절차

To a stirred solution of 3-bromothieno[2,3-b]pyridine (J-3) (107 mg, 0.5 mmol) and CuCN (60 mg, 0.67 mmol) in anhydrous DMF (4 mL) was added Pd(PPh3)4 (57 mg, 0.05 mmol). The reaction was degassed with nitrogen and stirred at 120° C. for 5 h. Then the cooled mixture was concentrated and purified by chromatography to afford the title compound. MS (m/z): 161 (M+1)+.
