Versuchsvorschrift

{trans-4-[(2-Chloro-5-nitro-pyrimidin-4-ylamino)-methyl]-cyclohexyl}-carbamic acid tert-butyl ester (200 mg, 0.52 mmol) was dissolved in CH2Cl2 (10 mL) and Et3N (0.289 mL, 2.07 mmol) was added. 3-Piperidin-1-yl-benzylamine (197 mg, 1.04 mmol) was dissolved in DMA:EtOH (2 mL, 1:1) and added to the reaction solution. The reaction was stirred at room temperature for 18 h. The volatiles were removed in vacuo and the crude was purified via flash chromatography (SiO2, 25-50% EtOAc:Hexanes then 5% MeOH:CH2Cl2) to afford 176 mg (63%) of (4-{[5-nitro-2-(3-piperidin-1-yl-benzylamino)-pyrimidin-4-ylamino]-methyl}-cyclohexyl)-carbamic acid tert-butyl ester
