To a solution of 5-chloro-1-(2,6-difluorophenyl)-7-(methylsulfinyl)-3,4-dihydropyrimido[4,5-d]pyrimidin-2(1H)-one (250 mg, 0.70 mmol) in DCM (10 mL) were added 4-(1-pyrrolidinyl)piperidine (323 mg, 2.1 mmol) and N,N-diisopropylethylamine (0.3 mL, 1.7 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 (253 mg, 81%). LC-MS m/z 449 (M+H)+
