Reaction Steps

A 20 ml acetic acid-10 ml THF mixed solution containing 500 mg of 2-{[4-(aminomethyl)phenyl]amino}-4-[(3-methylphenyl)amino]pyrimidine-5-carboxamide dihydrochloride was mixed with 5.76 g of potassium cyanate, which was added by dividing into 6 portions, at room temperature, followed by stirring for 6 hours. The reaction mixture was concentrated and then poured into water, and the precipitated solid was collected by filtration and washed with acetonitrile. The resulting solid was purified by a silica gel column chromatography (chloroform:methanol) to obtain 150 mg of 4-[(3-methylphenyl)amino]-2-[(4-ureidomethylphenyl)amino]pyrimidine-5-carboxamide as a pale yellow solid.
