Procedure
To a stirred solution of N-[4-Methyl-3-(1-methyl-7-methylsulfanyl-2,4-dioxo-1,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-3-yl)-phenyl]-3-trifluoromethyl-benzamide (184 mg, 0.37 mmol) in the mixed solvent of DMF (4 mL) and chloroform (4 mL) is added m-chloroperoxybenzoic acid (77% max., 97 mg, 44 mmol) and the mixture is stirred for 1 h at room temperature. The mixture is diluted with chloroform, and washed with 5% aqueous Na2S2O3 solution and saturated NaHCO3 solution. The organic layer is dried over MgSO4 and concentrated under reduced pressure to give N-[3-(7-Methanesulfinyl-1-methyl-2,4-dioxo-1,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-3-yl)-4-methyl-phenyl]-3-trifluoromethyl-benzamide (167 mg, 88%).
