실험 절차

[1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II) (13.7 mg, 0.019 mmol) was added to a solution of 3b (51.0 mg, 0.094 mmol), 3-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (24.3 mg, 0.103 mmol) and sodium carbonate (94.0 μL, of a 2.0 M aqueous solution, 0.188 mmol) in EtOH:toluene (1.25 mL of an 80:20 mixture, respectively) at rt. The resulting solution was heated to 125° C. in a sealed microwave vial for 12 min. After cooling to rt, the reaction mixture was filtered through a short column of Celite®, eluting with EtOAc. The filtrate was washed with water and brine, dried (sodium sulfate) and concentrated in vacuo. The crude residue was purified by preparative reversed phase HPLC on YMC Pack Pro C18 stationary phase (CH3CN/H2O as eluent, 0.05% TFA as modifier), followed by lyophilization of the purified fractions afforded the title compound 3c. m/z (ES) 572 (MH)+.
