6-(4-Aminophenoxy)pyrimidin-4-ylamine (88.9 mg, 0.440 mmol) and phenyl isocyanate (52.4 mg, 0.440 mmol) were stirred together for 3 hours in dimethylformamide (2 ml) at room temperature. The reaction solution was distributed between ethyl acetate and water, the organic layer was washed with water and saturated saline and dried over anhydrous magnesium sulfate, the drying agent was filtered off and the filtrate was distilled off under reduced pressure. The obtained crude product was suspended in ethyl acetate, the suspension was diluted with hexane, and the crystals were filtered out, washed with hexane and then blow-dried to obtain the title compound (98.0 mg, 0.305 mmol, 69%) as colorless crystals.
