Reaction Steps

4,6-Diiodopyrimidin-5-amine (2.2 g) was dissolved in 1-methyl-2-pyrrolidone (11.5 mL), phenol (656 mg) and potassium carbonate (964 mg) were added, and the mixture was stirred at 100° C. for 16 hrs. After cooling to room temperature, the mixture was diluted with ethyl acetate (200 mL) and washed successively with water (100 mL) and saturated brine (100 mL). The organic layer was dried over magnesium sulfate and concentrated under reduced pressure. The residue was separated and purified by silica gel column chromatography (eluent, hexane:ethyl acetate=80:20→20:80) to give the title compound (2.0 g) as an oil.
