To a solution of tert-butyl 4-(4-(9-chloro-3-methyl-2-oxo-3,4-dihydropyrimido[5,4-c]quinolin-1(2H)-yl)-2-(trifluoromethyl)phenyl)piperazine-1-carboxylate (57 mg, 0.1 mmol) and quinolin-3-ylboronic acid (26 mg, 0.15 mmol) in 1,4-dioxane (2 mL) at room temperature was added bischloroditriphenylphosphine (4 mg, 0.005 mmol), tert-butyl xphos (4 mg, 0.01 mmol), and Na2CO3 (0.3 mL, 0.3 mmol). The resultant solution was heated to 100° C. for 12 h before cooling to room temperature. The reaction mixture was filtered through celite. The solvent was removed in vacuo and the resulting crude residue was purified by flash column chromatography to afford the title product 32 mg (47%). LC-MS: (M+H)=668.38
