The synthetic route is as follows., COA of Formula: C7H13Br

Preparation of (S)-2-Cyclopentyloxycarbonylamino-9-(2-{[(lR,2S)-l-({(2S,4R)-4-[2-(2- isopropyl-amino-thiazol-4-yl)-7-methoxy-quinoIin-4-yloxy]-pyrrolidine-2-carbonyI}- amino)-2-vinyl-cycIopropane-carbonyl]-sulfamoyI}-phenyIamino)-nonanoic acid; Step 1; (2S,5R)-3,6-Diethoxy-2-hept-6-enyl-5-isopropyI-2,5-dihydro-pyrazine; A solution of 26.2 g (123 mmol) of (R)-3,6-Diethoxy-2-isopropyl-2,5-dihydro-pyrazine in 450 ml of abs. THF under argon is cooled to -75C and 77 mL (123 mmol) n-BuLi (1.6 M in Toluene) is added within 45 min while the temperature is maintained below -700C. A solution of 15 g (85 mmol) of 7-bromo-l-heptene in 80 ml of THF abs is added at -70C. The reaction mixture is stirred for 3h at -70C, for 17h at -4C and for 3h at RT. Ice-cold saturated NH4Cl (70 ml) and H2O (500 ml) are added and the resulting mixture is extracted with EtOAc (500 ml). The organic layer is washed with H2O. The combined aqueous phases are extracted with EtOAc (500 ml). The combined organic phases are dried over Na2SO4, concentrated in vacuo and the residue purified by FC on silica gel. (eluent: Hexane/EtOAc 30: 1) to give the title compound as a yellow oil. TLC, Rf (Hexane/ EtOAc 30:1) = 0.46 MS (method D): 309 [M+H]
