To a suspension of (6-bromo-4-((6-((2-(dimethylamino)ethyl)amino)pyridin-3-yl)amino)quinolin-3-yl)(cyclopropyl)methanone (91 mg, 0.20 mmol), 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (82 mg, 0.30 mmol) and Pd(dppf)Cl2 (14.6 mg, 0.02 mmol) in dioxane (6 mL) was added Cs2CO3 (1.0 M in H2O, 0.6 mL, 0.6 mmol). The reaction mixture was degassed with nitrogen and heated at 80° C. for 2 h. The solution was cooled to room temperature, diluted with a satd. aq. NaHCO3 solution and extracted with CHCl3/isopropanol (3:1). The combined organic layers were dried over anhydrous sodium sulfate, concentrated and purified by preparative HPLC (C18 silica, 10-90% acetonitrile/water with 0.05% TFA). The desired fractions were combined and concentrated. The residue was dissolved in methanol (4 mL) and HCl (1.25 M in methanol, 1.5 mL, 1.9 mmol) and the mixture was concentrated to give the desired product (97.7 mg, 78%) as an off-white solid. 1H NMR (500 MHz, MeOD) δ 9.38 (s, 1H), 8.32-8.17 (m, 3H), 8.04 (d, J=8.8 Hz, 1H), 7.73 (d, J=9.0 Hz, 1H), 7.31-7.23 (m, 2H), 7.01 (d, J=9.2 Hz, 1H), 3.87 (t, J=6.1 Hz, 2H), 3.44 (t, J=6.1 Hz, 2H), 2.98 (s, 6H), 2.89-2.80 (m, 1H), 1.24-1.18 (m, 4H). ESI MS m/z 520 [C28H27ClFN5O2+H]+; HPLC 97.9% (AUC), tR=9.99 min.
