Participants

Reaction Steps

5-Bromo-2-(2,2-dimethylmorpholino)pyridin-3-amine (0.087 g, 0.31 mmol), 4-chloro-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinoline (0.071 g, 0.25 mmol), and hydrochloric acid, 4.0M in 1,4-dioxane (0.07 mL, 0.28 mmol) were stirred in NMP (0.5 mL) then microwaved at 150° C. After 2 h, the reaction was diluted with EtOAc and washed once with satd aq. sodium bicarbonate and once with brine. After drying over anhydrous sodium sulfate, filtration, and concentration, the brown residue was purified with silica gel chromatography (0-40% EtOAc in hexanes) to yield mostly N-(5-bromo-2-(2,2-dimethylmorpholino)pyridin-3-yl)-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-amine. Mass Spectrum (ESI) m/e=540.1 (M+1).
