Versuchsvorschrift

(1R,2S)-ethyl-1-((2S,4R)-4-hydroxypyrrolidine-2-carboxamido)-2-vinylcyclopropanecarboxylate hydrochloride salt (WO2005095403) (1.04 g, 3.32 mmol), (S)-4-(N-(but-3-enyl)-2-nitrophenylsulfonamido)-2-(tert-butoxycarbonylamino)-butanoic acid (1.38 g, 3.02 mmol) and HATU (1.26 g, 3.32 mmol) in toluene (36 mL) and ACN (4 mL) was added DIEA (2.05 mL, 6.03 mmol) at 0° C. The reaction warmed to rt and stirred at rt for 1 hr. Ethyl acetate (50 mL) and water (20 mL) was added. The organic layer was separated and washed with brine, dried over sodium sulfate. After removal of solvent, the residue was purified by chromatography (Ethyl acetate) to give (1R,2S)-ethyl 1-((2S,4R)-1-((S)-4-(N-(but-3-enyl)-2-nitrophenylsulfonamido)-2-(tert-butoxycarbonylamino)butanoyl)-4-hydroxypyrrolidine-2-carboxamido)-2-vinylcyclopropanecarboxylate as white foam solid (1.63 g, 76%). MS: Calcd.: 707; Found: [M+H]+ 708.
