Reaction Steps

To the solution of 3-(8-(2,6-difluorophenyl)-2-{[2-(dimethylamino)ethyl]-amino}-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl)-5-fluoro-4-methylbenzoic acid (25 mg, 0.05 mmol) in CH2Cl2 (2 mL) were added methylamine (2.0 M soln. in THF, 0.13 mL, 0.26 mmol), triethylamine (0.05 mL, 0.36 mmol) and HBTU (20 mg, 0.053 mmol). The reaction mixture was stirred over night. The reaction mixture was concentrated. Separation via a HPLC with TFA followed by treatment with t-amino SPE cartridge then provided the title compound as a white solid (14 mg, 54%). LC-MS m/z 514 (M+H)+; 1H-NMR (MeOD) δ 2.24 (s, 3H), 2.78 (s, 6H), 2.94 (s, 3H), 3.15 (m, 2H), 3.55 (m, 2H), 4.22 (s, 2H), 7.18 (m, 2H), 7.56 (m, 2H), 7.39 (m, 1H).
