Reaktionsschritte

A flask containing 45 mg of palladium(II) acetate (0.2 mmol), 126 mg of BINAP (0.20 mmol) and 0.233 mg of sodium tert-butylate in dry toluene (15 mL) was flushed with nitrogen 1.275 g of 1-allylpiperazin (10 mmol) were added and the reaction mixture was heated to 50° C. 630 mg of 4-isopropyl-benzenesulfonic acid 6-chloro-pyridin-3-yl ester (2.0 mmol) were dissolved in toluene and the solution was slowly added over a period of 10 minutes into the reaction mixture with stirring. The mixture was heated to reflux with stirring for 7 h. Thereby 4-isopropyl-benzenesulfonic acid 6-(4-allyl-piperazin-1-yl)-pyridin-3-yl ester was obtained in 21% yield.
