Versuchsvorschrift

The reaction of 8.0 g (0.022 mole) of 2-tributylstannylpyridine with 4.92 g (0.020 mole) of ortho-nitroiodobenzene was carried out in the presence of 0.70 g (0.001 mole) of dichlorobis(triphenlylphosphine)palladium in 100 ml of tetrahydrofuran at 110° C. After 24 hours from the start of the reaction, a saturated aqueous sodium chloride solution was added to the reaction mixture and the reaction product was extracted with ether. The ether layer was then washed with a saturated aqueous sodium chloride solution, dried over magnesium sulfate and concentrated. The resulting liquid was purified by column chromatography and concentrated to give 0.96 g (0.0048 mole, 24.9%) of ortho-(2-pyridyl)nitrobenzene as brown liquid.
