Reaction Steps

To a solution of tert-butyl 4-(4-(9-chloro-2-oxo-2H-[1,3]oxazino[5,4-c]quinolin-1(4H)-yl)-2-(trifluoromethyl)phenyl)piperazine-1-carboxylate (56 mg, 0.1 mmol) and quinolin-3-ylboronic acid (25 mg, 0.15 mmol) in 1,4-dioxane (1 mL) at room temperature was added bischloroditriphenyl phosphine palladium (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 4 h and then allowed to cool to room temperature, filtered through celite, and washed with EtOAc (3×10 mL). After removal of solvent in vacuo, the residue was purified by flash column chromatography to afford the title compound (35 mg, 55%). LC-MS: (M+H)=630.30
