Reaction Steps

A solution of PdCl2(dppf)-CH2Cl2 adduct (0.095 g, 0.116 mmol), 2-(4-(difluoromethyl)-5-fluoro-2-methoxyphenyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (Intermediate SSSSS; 1.290 g, 4.27 mmol), 7-bromo-4-chloro-2-methylquinazoline (ACES Pharma, 1.000 g, 3.88 mmol), and potassium carbonate (2.147 g, 15.53 mmol) in 12 mL dioxane was treated with 4 mL water and was allowed to stir at room temperature overnight. LC/MS showed mostly product, so the reaction mixture was diluted with DCM and filtered through a plug of Celite. The aqueous layer was removed and the organics concentrated. The crude residue was carried on to step 2 without purification. (M+H)+=399.0.
