Reaction Steps

A mixture of N-(3-chloro-4-fluorophenyl)-6-iodo-2-(pyridin-3-yl)quinazolin-4-amine (1.0 g, 2.10 mmol), 3-chlorophenylboronic acid (0.49 g, 3.13 mmol), Pd(PPh3)4 (0.24 g, 0.210 mmol), K3PO4 (1.34 g, 6.31 mmol) in dioxane (20 mL) and water (2.0 mL) was stirred under reflux for 2 h. Ethyl acetate (20 mL) was added to the cooled mixture and filtered. The filtered solid was recrystallized from DMF and water to give the title compound (0.50 g, 51.6%). 1H NMR (400 MHz, DMSO) δ 10.20 (s, 1H), 9.54 (s, 1H), 8.87 (s, 1H), 8.74-8.65 (m, 2H), 8.31-8.23 (m, 2H), 8.04-7.85 (m, 4H), 7.64-7.49 (m, 4H).
