Versuchsvorschrift

To a solution of 2,4,5-trichloropyrimidine (1.46 g, 7.96 mmol) and tert-butyl 5-aminohexahydrocyclopenta[c]pyrrole-2(1H)-carboxylate (3.11 g, 13.74 mmol) in EtOH (60 mL) was added Et3N (2.21 g, 21.84 mmol) and the reaction mixture was stirred at rt overnight and then concentrated in vacuo. The residue was dissolved in a mixture of EtOAc (50 mL) and water (50 mL), and extracted with EtOAc (150 mL×3). The combined organic phases were washed with brine (150 mL), dried over anhydrous Na2SO4, then concentrated in vacuo. The residue was purified by silica gel column chromatography (EtOAc/PE (v/v)=1/5) to give the title compound as a pale yellow solid (2.97 g, 100%).
