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-(1-methylethyl)benzamide (20 mg, 0.04 mmol) in THF (3 mL) was added N,N-dimethyl-1,2-ethanediamine (0.022 mL, 0.20 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 (20 mg, 95%). LC-MS m/z 524 (M+H)+; 1H-NMR (MeOD) δ 1.27 (d, 6H), 2.14 (s, 6H), 2.33 (s, 3H), 2.37 (m, 2H), 3.22 (m, 2H), 4.09 (s, 2H), 4.23 (m, 1H), 7.15 (t, 2H), 7.46 (d, 1H), 7.52 (m, 1H), 7.69 (s, 1H), 7.85 (d, 1H).
