Procedure
A 2.5 dram reaction vial was charged with N-(3-chloro-4-fluorophenyl)-6-iodo-2-(pyridin-3-yl)quinazolin-4-amine (0.250 g, 0.524 mmol), 2-morpholinoethanol (1 ml, 8.17 mmol) as solvent, copper(I) iodide (0.020 g, 0.105 mmol), racemic-2,2′-diamino-1,1′-binaphthyl (0.030 g, 0.105 mmol), and cesium carbonate (0.513 g, 1.573 mmol). The reaction mixture was heated at 110° C. overnight. After cooling, water was added to the reaction mixture, and the resultant precipitate was collected by filtration. The solid residue was purified via ISCO (silica, 12 g column, 95% dichloromethane-5% methanol-0.1% NH4OH) to yield the desired compound as a brown solid. The solid was further washed with a mixture of water and saturated NaHCO3 solution and dried. The product off the column was further purified by prep TLC (silica gel, 1000 micron, 95% dichloromethane-5% methanol-0.1% NH4OH) to afford the desired product as a light brown solid (21.2 mg, 8%), LCMS m/z=480.0 (M+1) (Method C) (retention time=2.09 min). 1H NMR (300 MHz, DMSO) δ 9.81 (s, 1H), 9.47 (d, J=1.8 Hz, 1H), 8.66-8.57 (m, 2H), 8.21 (dd, J=6.8, 2.6 Hz, 1H), 7.92 (d, J=2.5 Hz, 1H), 7.87 (ddd, J=8.9, 4.3, 2.7 Hz, 1H), 7.81 (d, J=9.1 Hz, 1H), 7.57-7.47 (m, 3H), 4.25 (t, J=5.8 Hz, 2H), 3.64-3.55 (m, 4H), 2.78 (t, J=5.7 Hz, 2H), 2.55-2.49 (m, 4H).
