Procedure

To a solution of compound 3-[8-(2,6-difluorophenyl)-2-(methylsulfinyl)-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl]-N-(4-fluorophenyl)-4-methylbenzamide (10 mg, 0.018 mmol) in THF (5 mL) were added 1-methyl-4-piperidinamine (10 mg, 0.088 mmol) and N,N-diisopropylethylamine (0.1 mL, 0.574 mmol). The resultant solution was stirred at room temperature over might. The result mixture was concentrated. CombiFlash chromatography (mobile phase DCM/DCM[90]+MeOH[7]+NH4OH[3]) provided the title compound as a white solid (9 mg, 83%). LC-MS m/z 602 (M+H)+; 1H-NMR (MeOD) δ 1.47 (m, 2H), 1.84 (m, 4H), 2.24 (s, 3H), 2.33 (s, 3H), 2.79 (m, 2H), 3.20 (m, 1H), 4.13 (s, 2H), 7.15 (m, 4H), 7.53 (m, 2H), 7.72 (m, 2H), 7.82 (s, 1H), 7.98 (d, 1H).
