実験手順

To the suspension of NaH (60% dispersion in mineral oil, 19.7 mg, 0.49 mmol) in DMF is added N-[4-Methyl-3-(7-methylsulfanyl-2,4-dioxo-1,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-3-yl)-phenyl]-3-trifluoromethyl-benzamide (218 mg, 0.45 mmol) at 0° C. When H2 evolution has ceased, iodomethane (84 μl, 1.35 mmol) is added and the reaction mixture is stirred for 3 hours at room temperature. The mixture is diluted with ethyl acetate, and washed with 5% aqueous Na2S2O3 solution to remove DMF. The organic layer is dried over MgSO4 and concentrated under reduced pressure. The crude product is crystallized from MeOH to give 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, 82%) as a white solid.
