Reaction Steps

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-(1-methylethyl)-1,3-propanediamine (0.042 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 (13 mg, 39%). LC-MS m/z 554 (M+H)+; 1H-NMR (MeOD) δ 1.00 (m, 9H), 1.65 (m, 4H), 2.31 (s, 3H), 2.50 (m, 2H), 2.78 (m, 2H), 3.16 (m, 2H), 3.43 (m, 1H), 4.11 (s, 2H), 7.17 (t, 2H), 7.46 (d, 1H), 7.52 (m, 1H), 7.69 (s, 1H), 7.86 (d, 1H).
