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 (20 mg, 0.036 mmol) in THF(3 mL) was added N-(1,1-dimethylethyl)-1,3-propanediamine (0.028 mL, 0.177 mmol). The resultant solution was stirred at room temperature over night. The result mixture was concentrated. CombiFlash chromatography (mobile phase DCM/DCM[90]+MeOH[7]+NH4OH[3]) provided the title compound as a white solid (18 mg, 80%). LC-MS m/z 618 (M+H)+; 1H-NMR (MeOD) δ 1.11 (s, 9H), 1.58 (m, 2H), 2.34 (s, 3H), 2.48 (m, 2H), 3.15 (m, 2H), 4.13 (s, 2H), 7.15 (m, 4H), 7.53 (m, 2H), 7.72 (m, 2 H), 7.82 (s, 1H), 7.98 (d, 1H).
