N2-(4-Amino-phenyl)-5-bromo-N4-prop-2-ynyl-pyrimidine-2,4-diamine (100 mg, 0.3 mmole, prepared in analogy to procedure 21) was dissolved in acetonitrile (10 ml) and ethyl isocyanate (0.5 ml) was added at room temperature. The reaction mixture was heated under reflux for 5 hours and then cooled to room temperature and stirred overnight. The solid was filtered off and dried under high vacuum to provide 47 mg of 1-[4-(5-Bromo-4-prop-2-ynylamino-pyrimidin-2-ylamino)-phenyl]-3-ethyl-urea. ESI-MS: 390.
