실험 절차

5.06 g (24.5 mmol) of 2-chloro-5-nitroquinoline, 1.26 g (4.9 mmol) of triphenylphosphine and 8.0 g (25.2 mmol) of tri-n-butylvinyltin are dissolved in 60 ml of toluene. After adding 2.75 g (2.5 mmol) of tris(dibenzylidenacetone)dipalladium, the reaction mixture is allowed to reflux for 20 hours. Then, it is filtered on Celite and washed with ethyl acetate. The filtrate is mixed with saturated ammonium chloride solution. It is extracted with ethyl acetate, and the combined organic phases are dried on sodium sulfate. After the solvent is removed in a vacuum and after subsequent chromatography on silica gel with hexane-ethyl acetate (5-20%), 3.05 g (62% of theory) of the product is obtained.
