Versuchsvorschrift

2(S)-tert-butoxycarbonylamino-8-nonenoic acid (purchased from RSP Amino Acids)(1.0 g, 3.68 mmol) dissolved in 100 mL of DMF was treated sequentially with 1-{[4-(isoquinolin-1-yloxy)-pyrrolidine-2-carbonyl]-amino}-2-vinyl-cyclopropanecarboxylic acid ethyl ester, bis hydrochloride (1.46 g, 3.68 mmol), N-methyl morpholine (1.4 mL, 12.9 mmol), and HATU (PE biosystems) (1.68 g, 4.42 mmol). The reaction mixture was stirred at rt under N2 for 24 h, and then concentrated in vacuo. The residue was partitioned between ethyl acetate and pH 4 buffer (biphthalate). The organic phase was washed with sat. aq. NaHCO3, dried (MgSO4), and concentrated in vacuo to give 2.2 g of the crude product. Flash chromatography (20–50% ethyl acetate/hexane) gave 1.9 g (79%) of 1-{[1-(2-tert-butoxycarbonylamino-non-8-enoyl)-4-(isoquinolin-1-yloxy)-pyrrolidine-2-carbonyl]-amino}-2-vinyl-cyclopropanecarboxylic acid ethyl ester as a glassy colorless solid:
