Water → N-(4-(6-(4-Fluorophenylamino)pyrimidin-4-yloxy)phenyl)-N'-phenylurea

Participants

Reaction Steps

N-(4-(6-Chloropyrimidin-4-yloxy)phenyl)-N′-phenylurea (68.0 mg, 0.200 mmol) and 4-fluoroaniline (111 mg, 1.00 mmol) were heated and stirred in 1-methylpyrrolidone (1 ml) at 130° C. for 3 hours. The reaction solution was distributed between ethyl acetate and water, the organic layer was washed with saturated aqueous sodium bicarbonate, 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 (33.0 mg, 0.079 mmol, 40%) as colorless crystals.
