Procedure
In a 10 mL microwave vial was added 6-(3-(2-chloroethoxy)phenyl)-N-methyl-2-(pyridin-3-yl)quinazolin-4-amine (50.0 mg, 0.128 mmol), 2,2,2-trifluoroethylamine (0.100 ml, 1.279 mmol), potassium iodide (42.5 mg, 0.256 mmol), and N,N′-diisopropylethylamine (0.045 ml, 0.256 mmol) in DMF (3 mL) to give a yellow suspension. The vial was irradiated at 150° C. in the microwave for 20 min. Water (10 mL) was added to the mixture and extracted with ethyl acetate (2×20 mL). The organic layers were combined and washed with water (1×20 mL) and brine (1×20 mL), dried over MgSO4, filtered and concentrated. The residue was purified by column chromatography on silica gel (eluted with (CH2Cl2/CH2Cl2-MeOH-NH4OH=100:20:1 1:0 to 0:1). The product was converted to the HCl salt by addition of 4 M HCl-dioxane, then crystallization from IPA-H2O to give 30 mg of N-methyl-2-(pyridin-3-yl)-6-(3-(2-(2,2,2-trifluoroethylamino)ethoxy)phenyl)quinazolin-4-amine as a yellow powder (42%). LCMS m/z=454 (M+1) (Method C) (retention time=2.26 min). 1H NMR (300 MHz, DMSO) δ 10.73-10.36 (m, 1H), 9.65 (s, 1H), 9.13-8.98 (m, 2H), 8.93 (d, J=5.0 Hz, 1H), 8.38 (d, J=8.4 Hz, 1H), 8.24 (d, J=7.7 Hz, 1H), 7.94-7.75 (m, 1H), 7.69-7.41 (m, 3H), 7.09 (d, J=8.1 Hz, 1H), 4.61-4.43 (m, 2H), 4.28-4.07 (m, 2H), 3.59-3.39 (m, 2H), 3.30 (d, J=2.8 Hz, 3H).
