100 %Spectr. With palladium diacetate In water at 100℃; for 1 h; Inert atmosphere [0032] A mixture of 4-amino-2-bromopyridine (1.730 g, 10 mmol, 1.0 equiv), (0045) phenylboronic acid (1.341 g, 11 mmol, 1.1 equiv), Pd(OAc)2 ((0.0449 g, 0.2 mmol, 0.02 equiv) or (0.0898 g, 0.4 mmol, 0.04 equiv) as identified in Table 1) and H20 (25 mL, 1384 mmol) in a 3 -neck round-bottom flask was well stirred under reflux at 100 °C in a N2 atmosphere for the time listed in Table 1. The initial and final pH values of the aqueous phase were measured before and after the heating was enabled when the temperature was stabilized at 25 - 27 °C, and listed in Table 1. The initial reaction time (t = 0) was taken when the reaction mixture reached an internal temperature of 100 °C; the time to reach this temperature was approximately 20 - 30 minutes. The reactions were biphasic with an aqueous phase and a solid phase. The cooled reaction mixture was basified to pH > 12 using 30percent NaOH aqueous solution, and then thoroughly extracted with ethyl acetate. The combined organic phase was dried over anhydrous MgSC , filtered, and then concentrated in vacuo. The crude product was analyzed by GC and FontWeight="Bold" FontSize="10" Η NMR, as provided in Table 1.
