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]-4-methyl-N-propylbenzamide (30 mg, 0.06 mmol) in DCM (5 mL) was added N,N-dimethyl-1,3-propanediamine (0.036 mL, 0.30 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 (25 mg, 77%). LC-MS m/z 552 (M+H)+; 1H-NMR (MeOD) δ 1.00 (t, 3H), 1.58 (m, 2H), 1.66 (m, 2H), 2.16 (m, 2H), 2.18 (s, 6H), 2.30 (s, 3H), 3.06 (m, 2H), 3.37 (m, 2H), 4.10 (s, 2H), 7.17 (t, 2H), 7.45 (d, 1H), 7.53 (m, 1H), 7.69 (s, 1H), 7.85 (d, 1H).
