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 (80 mg, 0.16 mmol) in DCM (5 mL) was added 4-(1-pyrrolidinyl)piperidine (74 mg, 0.48 mmol). The resultant solution was stirred at room temperature over might. The result mixture was concentrated. CombiFlash chromatography (mobile phase DCM/DCM [90]+MeOH[7]+NH4OH[3]) provided the title compound as a white solid (75 mg, 79%).
