实验步骤: A vessel capable of sealing was charged with a mixture of 3-bromo-7-chlorothieno[3,2-b]pyridine (123 mg, 0.495 mmol), 4-fluoro-2-(trifluoromethyl) phenylboronic acid (123 mg, 0.594 mmol), PdCl2(dppf)-CH2Cl2 adduct (20.21 mg, 0.0.025 mmol), dioxane (6 mL), and a 2.0 M aqueous solution of K3PO4 (0.74 mL, 1.485 mmol) and was purged with nitrogen for 10 min. The vessel was sealed and heated at 90° C. for 3 hours. Upon cooling, the reaction mixture was diluted with CH2Cl2 and filtered with CH2Cl2/MeOH washing. The filtrate was concentrated under reduced pressure. The residue was dissolved in CH2Cl2 and washed with water, brine, dried over anhydrous Na2SO4 and concentrated under reduced pressure. The crude material was purified by BIOTAGE® eluting with 40%-60% CH2Cl2/hexanes at 30 mL/min. Concentration of appropriate fractions provided the title compound (150 mg, 91% yield) as a white solid.
