59% | With potassium phosphate; tris-(dibenzylideneacetone)dipalladium(0); In 1,4-dioxane; water; at 100.0℃;Inert atmosphere; | Pd2(dba)3 (176.56 mg, 0.19 mmol) and Xphos (183.83 mg, 0.39 mmol) were added to a solution of <strong>[130284-52-5]6-bromo-5-chloropyridin-3-amine</strong> (800 mg, 3.86 mmol), 1 -methyl-3-(4,4,5,5-tetramethyl-i ,3,2-dioxaborolan-2-yl)-1H-pyrazole (1203.52 mg, 5.78 mmol) and K3P04 (2.456 g,11.57 mmol) in dioxane/H20 (6/1, 20 mE) under an N2 atmosphere. The mixture was stirred at 1000 C. overnight. The reaction solution was filtered and the filtrate was concentrated to give a crude product. The crude product was purified by column chromatography over silica gel (petroleum ether/ethyl acetate from 100/0 to 0/100). The desired fractions were collected and the solvent was concentrated under reduced pressure to afford 1 57a (530 mg, 5 9.0% yield) as a yellow solid. ECMS (ESI) mlz M+i: 209.1. |

67% | With 1,1'-bis-(diphenylphosphino)ferrocene; dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; triethylamine; In toluene; at 70.0℃; under 1810.07 Torr; | A mixture of <strong>[130284-52-5]6-bromo-5-chloropyridin-3-amine</strong> (500 mg, 2.41 mmol), 1,1-bis(diphenylphosphino)ferrocene (134 mg, 0.24 mmol) and triethylamine (732 mg, 7.23 mmol) in MeOH (3 mL) and toluene (15 mL) was heated at 70 C. under a CO (35 psi) atmosphere with dichloro[1,1'-bis(diphenylphosphino)ferrocene]palladium(II) dichloromethane adduct (catalyst, 197 mg, 0.24 mmol), and the mixture was stirred overnight. After uptake of CO (1 equiv), the catalyst was removed by filtration and the filtrate was concentrated under reduced pressure to give a crude product. The crude product was purified by flash column chromatography over silica gel (petroleum ether/ethyl acetate from 100/0 to 50/50) to afford compound 43a as a red solid (300 mg, 67%). 1H NMR (400 MHz, CDCl3) delta ppm 3.96 (s, 3H), 4.14-4.24 (m, 2H), 7.03 (d, J=2.26 Hz, 1H), 8.03 (d, J=2.51 Hz, 1H). |
