Versuchsvorschrift

To a sealable vessel was added 4-(tert-butyldimethylsilyloxy)cyclohex-1-enyl trifluoromethanesulfonate (1.90 g, 5.27 mmol), sodium carbonate as a 2N solution in water (7.91 mL, 15.81 mmol), and 2-fluoropyridin-3-ylboronic acid (0.891 g, 6.33 mmol) before adding tetrakis(triphenylphosphine)palladium(0) (0.305 g, 0.264 mmol) under argon. The reaction mixture was sealed and set stirring at 80° C. After complete consumption of starting material, the black mixture was diluted with water before extracting with dichloromethane, drying over sodium sulfate, filtering, and concentrating under reduced pressure to an orange oil, which was used without purification. MS (ESI, pos. ion) m/z: 308.0 (M+1).
