반응 단계
A mixture of 3-tributylstannanyl-pyridine (255 mg, 0.693 mmol), 3-Bromo-pyridine-2-carbaldehyde (123 mg, 0.660 mmol), and Pd(PPh3)4 (53.1 mg, 0.046 mmol) in toluene (4 mL) was heated to 90° C. for 23 h and cooled to room temperature. The reaction mixture was diluted with EtOAc (50 mL), washed with brine (3×20 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure. Purification by flash chromatography on silica gel (Hexanes/EtOAc, 70:30, then 0:100) afforded [3,3′]Bipyridinyl-2-carbaldehyde (35 mg, 29%) as a yellow oil.
