Procedure

To a resealable tube was added a mixture of 3-(2-aminoquinazolin-6-yl)-4-methylpyridin-2(1H)-one (0.050 g, 0.20 mmol), potassium phosphate (0.084 g, 0.40 mmol), and copper(I) iodide (0.0075 g, 0.040 mmol) followed by Dioxane (2 mL), 1-chloro-3-iodobenzene (0.027 ml, 0.22 mmol) and N1,N2-dimethylethane-1,2-diamine (0.009 ml, 0.079 mmol). The resealable tube was purged with argon, sealed, and heated at 85° C. for 48 hrs. The crude mixture was filtered and concentrated in vacuo. The residue was purified by silica gel chromatography using 3-10% MeOH in CH2Cl2 with 1% NH4OH to afford 3-(2-amino-6-quinazolinyl)-1-(3-chlorophenyl)-4-methyl-2(1H)-pyridinone as an off-white solid. M+H+=363.1.
