Reaction Steps

To a 50 mL round bottom flask, 4-(2-chloro-6-fluoro-7-(3-(methylsulfonyl)phenyl)quinazolin-4-yl)morpholine (0.06 g, 0.00015 mol), (2-aminopyrimidin-5-yl)boronic acid (0.03 g, 0.00023 mol), cesium carbonate (0.097 g, 0.0003 mol), DMF (5 mL) and water (2 mL) were added. The reaction vessel was degassed with N2 for 5-10 minutes. To the same reaction mixture, Pd(PPh3)2Cl2 (0.005 g, 0.0000075 mol) was added and again degassed with N2 for 5-10 minutes. The reaction mixture was stirred at 95° C. for 2 hours. The reaction mixture was cooled and water was added. The crude product was extracted with ethyl acetate. The organic layer was washed with water, brine and dried over sodium sulfate. The solvent was removed under the reduced pressure to afford the crude product. The crude product was purified by column chromatography (60-120 silica gel, 0-5% methanol in chloroform) to provide the desired product (0.05 g, 7%). 1H NMR (400 MHz, DMSO-d6): δ 9.22 (s, 2H), 8.36 (s, 1H), 8.25 (s, 1H), 8.22 (d, J=2.0 Hz, 1H), 8.15 (d, J=8.8 Hz, 1H), 8.01 (d, J=8.0 Hz, 1H), 7.87-7.80 (m, 2H), 7.21 (s, 2H), 3.85 (s, 8H); 1H NMR (400 MHz, DMSO-d6+D2O): δ 9.12 (s, 2H), 8.20 (s, 1H), 8.14-8.06 (m, 3H), 7.95 (d, J=7.6 Hz, 1H), 7.79 (t, J=7.2 Hz, 2H), 3.83-3.77 (m, 8H), 3.21 (s, 3H). LC-MS (ESI): Calculated mass: 462.1; Observed mass [M+H]+: 463.1 (RT=0.23 min).
