実験手順

A dry flask containing 5-bromo-2-(4-methoxyphenyl)pyridin-3-amine (0.14 g, 0.52 mmol) in dry DMF (5.0 mL) was cooled to 0° C., then sodium hydride, 60% dispersion in mineral oil (0.043 g, 1.07 mmol) was added carefully in portions. The mixture was stirred at 0° C. for 15 min, then 4-chloro-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinoline (0.18 g, 0.62 mmol) was added in portions. Upon complete addition, the mixture was warmed to 60° C. After 18 h, the reaction was cooled to rt then was carefully treated with 10% sodium carbonate solution. The black mixture was subsequently extracted five times with DCM:MeOH (90:10). The organic extraction was then washed one time with brine and dried over anhydrous magnesium sulfate. After filtration and concentration, the black residue was purified on silica gel (50-100% EtOAc in hexanes) to afford a mostly N-(5-bromo-2-(4-methoxyphenyl)pyridin-3-yl)-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-amine. Mass Spectrum (ESI) m/e=533.0 (M+1).
