Reaction Steps

To an 8 mL screw-cap vial was added 6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinazolin-4-amine (26 mg; 0.096 mmol, 26 mg) followed by 4-bromo-N-(2-pyrrolidin-1-ylethyl)pyridin-2-amine (2 equiv., 0.19 mmol, 52 mg, Bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (0.05 equiv., 0.005 mmol, 4 mg, dioxane (0.4 mL), and potassium phosphate tribasic (2M in water, 4 equiv., 0.38 mmol, 0.19 mL). The reaction was capped and shaken for 1 h at 100° C. The reaction was then cooled to room temperature, then extracted. The aqueous was further extracted with dichloromethane, and combined with the dioxane extract and concentrated. The crude was purified by reverse phase HPLC, yielding 5 mg of desired product. 1H NMR (400 MHz, DMSO) δ 8.62-8.56 (s, 1H), 8.42-8.38 (s, 1H), 8.32-8.16 (m, 2H), 8.11-8.02 (m, 2H), 7.77-7.72 (d, J=8.7 Hz, 1H), 6.98-6.92 (d, J=5.4 Hz, 1H), 6.90-6.84 (s, 1H), 6.53-6.44 (t, J=5.4 Hz, 1H), 3.49-3.40 (t, J=6.7 Hz, 2H), 2.73-2.65 (t, J=6.7 Hz, 2H), 2.64-2.55 (m, 4H), 1.80-1.63 (m, 4H).
