Reaction Steps

To a solution of 2-chloro-5-phenyl-N-(pyridin-2-ylmethyl)quinazolin-4-amine (80 mg, 0.23 mmol) in 1,4-dioxane (6 mL) and H2O (0.5 mL) under nitrogen was added 3-(2,2-dimethyl-1,3-dioxan-5-yl)-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (110 mg, 0.35 mmol), and potassium carbonate (96 mg, 7.0 mmol). The mixture was degassed with nitrogen for 15 min. (1,1′-Bis(diphenylphosphino)ferrocene)palladium (II) chloride dichloromethane complex (12 mg, 0.015 mmol) was added and the reaction mixture was again degassed for 10 min with nitrogen. The reaction mixture was stirred at 90° C. for 16 h, then allowed to cool to room temperature and quenched by the addition of water. The reaction mixture was extracted with ethyl acetate. The combined organic portions were washed with water and saturated NaCl, dried over Na2SO4, filtered and concentrated under reduced pressure. The resulting residue was purified by column chromatography using 20% EtOAc in hexanes to provide 2-(5-(2,2-dimethyl-1,3-dioxan-5-yl)pyridin-3-yl)-5-phenyl-N-(pyridin-2-ylmethyl)quinazolin-4-amine (45 mg, 39%). LCMS Method T: retention time 1.75 min; [M+1]=504.2.
