反応手順
A mixture of 3-bromo-6-methylpicolinonitrile (1 g, 5.1 mmol), 2-(tributylstannyl)pyridine (2.43 ml, 6.60 mmol), cesium fluoride (150 mg, 10.2 mmol), CuI (193 mg, 1.02 mmol) and Pd(PPh3)4 (586 mg, 0.51 mmol) in DMF (10 mL) was degassed and heated at 120° C. for 1 h in a microwave reactor. The solvent was removed in vacuo to obtain the crude which was purified by silica gel chromatography (0˜100% DCM/EtOAc) to yield the title compound as a brown oil (0.87 g, 88%). MS (ESI) 196 (M+H).
