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 (30 mg, 0.06 mmol) in THF (3 mL) was added N-(1-methylethyl)-1,2-ethanediamine (0.019 mL, 0.15 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 (23 mg, 71%).
