Reaction Steps

To a solution of compound 5.6 1-(4-(4-propionylpiperazin-1-yl)-3-(trifluoromethyl)phenyl)-9-(quinolin-3-yl)-1H-[1,3]oxazino[5,4-c]quinoline-2,4-dione (20 mg, 0.032 mmol, 1 equiv.) in THF/CH2Cl2 (5 mL, 1:1) at room temperature was added MeNH2 (5 mg, 0.16 mmol, 5 equiv.). The resulting solution was heated to 40° C. and stirred for 2 h. Upon concentration, the mixture was purified via preparative LC-MS (CH3CN:H2O) to furnish the desired compound 5.7 3-methyl-1-(4-(4-propionylpiperazin-1-yl)-3-(trifluoromethyl)phenyl)-9-(quinolin-3-yl)pyrimido[5,4-c]quinoline-2,4(1H,3H)-dione (3 mg). LC-MS (M+H): 639.49
