YieldReaction ConditionsOperation in experiment
78% With potassium phosphate; dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; In tetrahydrofuran; at 80℃;Inert atmosphere; Sealed tube; A 150 mL pressure flask was charged with (6-chloro-2-methoxypyridin-3- yl)boronic acid (2.5 g, 13.3 mmol) and 2,5-dibromo-3-nitropyridine (3.38 g, 12.01 mmol). The solids were suspended in THF (60 mL). The mixture was treated with PdCl2(dppf)-CH2Cl2 adduct (0.545 g, 0.667 mmol) and K3P04 (2M, 20 mL, 40 mmol). Argon was bubbled through the mixture for 5 min while sonicating. The flask was capped and heated to 80C in a preheated oil bath. The reaction was cooled to room temperature. The reaction mixture was filtered and the filtrate was concentrated to remove THF. The remaining water layer was diluted further with water and was extracted with ethyl acetate. The organic layer was dried over MgS04, filtered and concentrated under vacuum to give a solid. The material was taken up in DCM and a minimum of ethyl acetate and purified by flash column chromatography (80g ISCO column, 0-30% ethyl acetate/hexanes over 600 mL, then 50-100% over 300 mL). Like fractions were concentrated to give 4.5g (78%). NMR (400MHz, CDCh) delta 8.94 (d, J=2.0 Hz, 1H), 8.44 (d, J=2.0 Hz, 1H), 7.97 (d, J=8.0 Hz, 1H), 7.14 (d, J=7.8 Hz, 1H), 3.89 (s, 3H).

YieldReaction ConditionsOperation in experiment
To a mixed solution of compound 1b (5 g, 22 mmol), bisboronic acid pinacol (8.5 g, 33 mmol) and KOAc (3.2g, 33 mmol) in 1,4 dioxane (50 ml) was added Pd(dppf)2Cl2 (1g), and flushed with nitrogen. The reaction flask wassealed and the reaction was stirred overnight at 85°C. After cooling to room temperature, an aqueous Na2CO3 solution(2.5M, 10ml), Pd(dppf)2Cl2 (1g) and 2,5-dibromo-3-nitropyridine (9 g, 33 mmol) were added. After flushed with nitrogenfor 10 minutes, the reaction flask was sealed and the mixture was stirred overnight at 85°C. The reaction was pouredinto water and extracted with ethyl acetate. The organic phase mixture was dried over Na2SO4, dried by suction andpurified by silica gel column chromatography (PE:EA=10:1 to 1:1) to provide compound 1c as a yellow solid.HNMR(CDCl3),9.0(s,1H),8.4(s,1H),8.0(d,1H),7.6-7.7(m,2H),4.5(s,2H),3.3(s,3H).MS(ESI)m/z :347.9(M+H)+.
