Reaction Steps

To a mixture of 4,5-bis(diphenylphosphino)-9,9′-dimethylxanthene (521 mg, 0.90 mmol), tris(dibenzylideneacetone)dipalladium (0)-chloroform adduct (311 mg, 0.30 mmol), sodium t-butoxide (2.16 g, 23 mmol) and anhydrous toluene (37 ml) were added 3-bromopyridine (1.5 ml, 15 mmol) and diethylamine (1.9 ml, 18.0 mmol). The mixture was heated to 70° C., and the mixture was stirred for 3 hrs and at room temperature overnight. Water and ethyl acetate were added to the reaction mixture. The mixture was stirred, stood still and partitioned. The aqueous layer was extracted with ethyl acetate, and the combined organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and concentrated. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:1→2:1) to give N,N-diethylpyridin-3-amine (820 mg, yield 36%) as a brown oil.
