実験手順

To a stirred solution of 4-amino-2-methylsulfanyl-pyrimidine-5-carboxylic acid [2-methyl-5-(3-trifluoromethyl-benzoylamino)-phenyl]-amide (286 mg, 0.62 mmol) and diisopropylethylamine (864 μL, 4.96 mmol) in dioxane (10 mL) is added a solution of triphosgene (184 mg, 0.62 mmol) in dioxane (2 mL) at 0 C, and the mixture is stirred for 12 h at 100° C. The reaction mixture is diluted with EtOAc (50 mL), and washed with saturated NaHCO3 solution. The organic layer is dried over MgSO4, filtered, concentrated under reduced pressure, and crystallized from MeOH to give N-[4-Methyl-3-(7-methylsulfanyl-2,4-dioxo-1,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-3-yl)-phenyl]-3-trifluoromethyl-benzamide (166 mg, 55%) as a white crystalline solid.
