To a solution of 5-chloro-1-(2,6-difluorophenyl)-7-(methylsulfinyl)-3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one (800 mg, 2.23 mmol) in DCM (45 mL) were added N,N-dimethylethylenediamine (0.36 mL, 3.23 mmol) and triethylamine (0.63 mL, 4.5 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 (730 mg, 85%). LC-MS m/z 383 (M+H)+.
