Versuchsvorschrift

To a stirred solution of N-(3,4-dichlorophenyl)piperazine-1-carboxamide (2.00 g, 7.30 mmol) in DMF (150 ml) was added DIPEA (3.8 ml, 21.9 mmol), 3-carboxy-N-boc-proline (Arch Corporation) (1.727 g, 8.02 mmol) and HATU (3.051 g, 8.02 mmol) and the reaction stirred at ambient temperature for overnight (convenience). The solvents were then removed under reduced pressure. The resulting gum was then partitioned between EtOAc and water, extracted, the organic phase washed with saturated sodium bicarbonate solution and evaporated to dryness. The resulting foam was then purified on Isco™ Companion (40 g column:EtOAc) to give the product tert-butyl 3-[(4-{[(3,4-dichlorophenyl)amino]carbonyl}piperazin-1-yl)carbonyl]pyrrolidine-1-carboxylate as a pale yellow foam (3.396 g, 7.20 mmol, 99%).
