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 (36 mg, 0.072 mmol) in THF (2 mL)/CHCl3 (2 mL) were added 4-methyl-1,4′-bipiperidine (40 mg, 0.22 mmol) and N,N-diisopropylethylamine (0.1 mL, 0.5 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 (31 mg, 70%).
