Procedure

A solution of N-(5-bromo-2-morpholinopyridin-3-yl)-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-amine (395 mg, 0.77 mmol; described herein), 4,4,4′,4′,5,5,5′,5′-octamethyl-2,2′-bi(1,3,2-dioxaborolane) (215 mg, 0.85 mmol), bis(tricyclohexylphosphine)palladium(o) (25.7 mg, 0.039 mmol), potassium acetate (113 mg, 1.16 mmol), and 1,4-dioxane (10.6 mL) was stirred at 93° C. for 24 h. The reaction was then cooled to rt and partitioned between EtOAc and water. The organic layer was dried (magnesium sulfate) and concentrated, and chromatography afforded 5-(5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-ylamino)-6-morpholinopyridin-3-ylboronic acid as a yellow solid. Mass Spectrum (ESI) m/e=478.1 (M+1).
