Reaction Steps

In a 10 mL microwave vial was added 2-chloro-6-(3-methoxyphenyl)-N-methylquinazolin-4-amine (0.080 g, 0.267 mmol), pyrimidine-5-boronic acid (0.099 g, 0.801 mmol), dichlorobis(triphenylphosphine)palladium (II) (Pd(PPh3)2Cl2) (9.37 mg, 0.013 mmol), and potassium carbonate (0.111 g, 0.801 mmol) in DME (3 mL), EtOH (1.286 mL), and water (0.857 mL) to give a yellow suspension. The vial was irradiated at 120° C. for 15 min under argon. Water (10 rill) was added to the mixture and extracted with ethyl acetate (2×10 mL). The organic layers were combined and washed with brine (1×20 mL) and then dried over MgSO4, filtered and concentrated. The residue was washed with MeOH-CH2Cl2 and dried to give 35 mg of 6-(3-methoxyphenyl)-N-methyl-2-(pyrimidin-5-yl)quinazolin-4-amine as a white solid (38%). LCMS m/z=344 (M+1) (Method D) (retention time=1.78 min) 1H NMR (300 MHz, DMSO) δ 9.79-9.59 (m, 2H), 9.30 (s, 1H), 8.72 (d, J=4.6 Hz, 1H), 8.59 (s, 1H), 8.16 (d, J=8.6 Hz, 1H), 7.85 (d, J=8.7 Hz, 1H), 7.53-7.28 (m, 3H), 7.00 (d, J=6.8 Hz, 1H), 3.86 (s, 3H), 3.18 (d, J=3.9 Hz, 3H).
