실험 절차

A mixture of 6-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)furo[2,3-c]pyridin-7-one (50 mg, 0.18 mmol), 3-(cyclopropylmethoxy)-2-iodo-6-methylsulfonylpyridine (53 mg, 0.15 mmol), K3PO4 (114 mg, 0.54 mmol), Pd(dppf)Cl2 (13 mg, 0.018 mmol) in dioxane (5 mL) was bubbled with nitrogen for 5 min and then stirred at 70° C. for 12 h. The reaction mixture was concentrated, treated with DCM (30 mL), washed with water (30 mL) and brine (30 mL), dried over Na2SO4, filtered and concentrated. The residue was purified by prep-HPLC to give the title compound (35 mg, yield: 52%) as an off-white solid.
