実験手順

0.25 g (0.5 mmol) trans-(4-{4-[2-(4-amino-cyclohexyl)-ethyl]-piperazin-1-yl}-5,6-dichloro-pyrimidin-2-yl)-methyl-amine trihydrochloride was dissolved in dry dichloromethane (10 ml). Triethylamine (0.28 ml, 2 mmol) was added followed by the addition of ethylisocyanate (0.06 ml, 0.753 mmol), and the reaction mixture was stirred at room temperature for 4 hours. The solvent was removed in vacuo. The residue was triturated with water, and the precipitate was filtered to give the title compound (0.17 g, 72%) MS (EI): 459.2 (MH+). 1H NMR (300 MHz, DMSO-d6 (TMS)+1 drop of cc. DCl, (ppm)): 0.96 t (3H); 0.88-1.13 m (4H); 1.13-1.31 m (1H); 1.54-1.85 m (6H); 2.74 s (3H); 2.98 q (2H); 2.89-3.16 m (4H); 3.19-3.33 m (1H); 3.34-3.58 m (4H); 4.12-4.30 m (2H).
