実験手順

Under a nitrogen atmosphere, to 6-amino-3-cyclopropyl-1-(2-fluoro-4-iodo-phenyl)-1H-pyrimidine-2,4-dione 75 (178 g) were added N,N-dimethylformamide (356 ml) and N,N-dimethylformamide dimethylacetal (178 ml), and the mixture was stirred at room temperature for 2 hrs. Isopropanol (178 ml) was added with stirring at room temperature, and water (1068 ml) was added dropwise. The mixture was stirred at room temperature for 2 hrs, and the precipitated crystals were collected by filtration and dried to give N′-[1-cyclopropyl-3-(2-fluoro-4-iodo-phenyl)-2,6-dioxo-1,2,3,6-tetrahydro-pyrimidin-4-yl]-N,N-dimethyl-formamidine 76 (188 g, yield 92%) as yellow crystals.
