Reaction Steps

To a suspension of 1-(6-bromo-4-((trans-4-(2-(dimethylamino)ethyl)cyclohexyl)amino)quinolin-3-yl)ethanone (63 mg, 0.15 mmol), 2-chloro-6-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (61 mg, 0.22 mmol) and Pd(dppf)Cl2 (11 mg, 0.015 mmol) in dioxane (4 mL) was added Cs2CO3 (1.0 M in H2O, 0.4 mL, 0.4 mmol). The reaction mixture was degassed with nitrogen and heated at 80° C. for 2 h. The reaction mixture was cooled to room temperature, diluted with a satd. aq. NaHCO3 (20 mL) and extracted with ethyl acetate. The combined organic layers were dried over anhydrous sodium sulfate, concentrated and purified by preparative HPLC (C18 silica, 10-90% acetonitrile/water with a mixture of CHCl3/isopropanol (3:1). The desired fractions were concentrated and dissolved in methanol and resultant residue was dissolved in methanol (4 mL) and HCl (1.25 M in methanol, 1.5 mL, 1.9 mmol) was added. The resulting solution was concentrated to give the desired product (55.9 mg, 67%) as an off-white solid NMR (500 MHz, MeOD) δ 9.10 (s, 1H), 8.50 (s, 1H), 8.27 (dd, J=8.7, 1.7 Hz, 1H), 7.97 (d, J=8.7 Hz, 1H), 7.59 (s, 1H), 7.52 (dd, J=11.4, 2.3 Hz, 1H), 4.54-4.50 (m, 1H), 3.25-3.17 (m, 2H), 2.90 (s, 6H), 2.73 (s, 3H), 2.42 (d, J=12.2 Hz, 2H), 2.04 (d, J=12.9 Hz, 2H), 1.80-1.68 (m, 4H), 1.59 (br s, 1H), 1.39-1.27 (m, 2H). ESI MS m/z 484 [C27H31ClFN3O2+H]+; HPLC>99% (AUC), tR=10.01 min.
