100 mg (0.26 mmol) of N-[3-methoxycarbonyl-phenyl]-4-[2-(3-hydroxy-propyl-amino)-4-pyridyl]-2-pyrimidineamine and 0.5 ml of 1,3-diamino-propane are stirred for 24 h at 90° and then diluted with 20 ml of ethyl acetate and extracted with 2×10 ml of sodium chloride solution. The organic phase is dried, concentrated and crystallised from methylene chloride/diethyl ether to give N-[3-{N-(3-amino-propyl)-aminocarbonyl}-phenyl]-4-[2-(3-hydroxy-propyl-amino)-4-pyridyl]-2-pyrimidineamine;
