실험 절차

To a stirred solution of N-{3-[(2-chloro-4-methylaminopyrimidin-5-ylmethyl)amino]-4-methylphenyl}-3-trifluoromethylbenzamide (559 mg, 1.24 mmol) and triethylamine (693 μL, 4.97 mmol) in THF (15 mL) is added triphosgene (147 mg, 0.49 mmol) in THF (5 mL) at 0° C., and the mixture is stirred for 30 minutes at room temperature. The precipitate is filtered off and the filtrate is stirred for 3 hours at 110° C. The reaction mixture is then diluted with EtOAc and washed with saturated NaHCO3. The organic layer is dried over MgSO4 and concentrated under reduced pressure to give crude oil which is purified by flash column chromatography (SiO2, EtOAc/hexane=1/2) to give N-[3-(7-chloro-2-oxo-1,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-3-yl)-4-methylphenyl]-3-trifluoromethylbenzamide (420 mg, 71%) as a white solid.
