A solution of PdCl2(dppf)-CH2Cl2 adduct (0.072 g, 0.088 mmol), 3-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (Intermediate GGGG) (0.500 g, 1.930 mmol), 7-bromo-4-chloro-2-methylquinazoline (0.452 g, 1.754 mmol), and potassium carbonate (0.970 g, 7.02 mmol) in 3 mL dioxane was treated with 1 mL water and was allowed to stir at room temperature 3 hours. LC/MS showed mostly product, so the reaction mixture was diluted with DCM and washed with water. The aqueous layer was removed and the reaction mixture was concentrated. The crude residue was carried forward to step 2 without purification. (M+H)+=354.0.
