Reaktionsschritte

This Example was carried out in the same manner as Example 1, except that 5.0 g (0.032 mol) of 2-chloro-phenyl boronic acid, 10.0 g (0.064 mol) of 3-bromopyridine, 150□ of tetrahydrofuran and 2M potassium carbonate solution (20□) were added and then 0.37 g (3 mol %) of palladium tetrakistriphenylphosphine [(pd(PPh3)4] was used as a catalyst. Finally, after the resulting solution was heated to reflux at 80° C. for 24 hours, the 2-(2-chloro-phenyl)pyridine was isolated. The yield was 50%.
