Reaction Steps

A 147 mg portion of potassium cyanate and 450 μl of 4 M hydrochloric acid-dioxane solution were added to a mixture of 312 mg of 2-(2-aminoethylamino)-4-(3-methylanilino)pyrimidine-5-carboxamide and 3 ml of water and 3 ml of 1,4-dioxane, followed by stirring at room temperature for 1 day. The reaction mixture was alkalified by adding 1 M sodium hydroxide aqueous solution, and the thus formed precipitate was collected by filtration. The filtered material was washed by stirring it in methanol while heating and then collected by filtration to obtain 212 mg of 4-(3-methylanilino)-2-[(2-ureidoethyl)amino]pyrimidine-5-carboxamide (colorless solid).
