Reaktionsschritte
To a mixture of 600 mg (2.5 mmol) of 2,6-dibromopyridine in 15 mL of toluene was added a mixture of 150 mg (1.27 mmol) of phenylboronic acid in 5 mL of methanol, 86 mg (0.075 mmol) of Pd(PPh3)4 and 15 mL of 2 M Na2CO3. The mixture was refluxed overnight, cooled, extracted with ethyl acetate, dried and 2-bromo-6-phenylpyridine isolated chromatographically from unreacted 2,6-dibromopyridine and 2,6-diphenylpyridine.
