2,4-Dibromothiophene (695 mg, 2.87 mmol), 2-(tri-n-butylstannyl)pyridine (830 mg, 1.92 mmol), and tetrakis(triphenylphosphine)palladium (0) (220 mg, 0.19 mmol) were refluxed in 3 mL of toluene at 120° C. overnight. After filtrated out of solid residue, the reaction mixture was purified by flash chromatography using a gradient of ethyl acetate in hexane to give a beige solid as the title compound (340 mg), m/z 240, 242 (MH+).
