To a slurry of (2S,4R)-4-(allylthio)-4-(biphenyl-4-yl)-1-((S)-2-(tert-butoxycarbonylamino)-3,3-dimethylbutanoyl)pyrrolidine-2-carboxylic acid (55.3 mg, 0.10 mmol), (1R,2R)-1-amino-2-(difluoromethyl)-N-(1-(hept-6-enyl)cyclopropylsulfonyl)cyclopropanecarboxamide (38.7 mg, 0.10 mmol) and HATU (57.0 mg, 0.150 mmol) in DCM (2 mL) was added N,N-Diisopropylethylamine (0.087 mL, 0.500 mmol). The formed solution was stirred at room temperature overnight. Diluted with DCM, washed with 1M HCl and brine, dried over MgSO4, filtered, and concentrated. The residue was purified by Biotage column, eluted with gradient 5%˜30% Acetone-Hexane to afford the desired product tert-butyl (S)-1-((2S,4R)-4-(allylthio)-4-(biphenyl-4-yl)-2-((1R,2R)-2-(difluoromethyl)-1-(1-(hept-6-enyl)cyclopropylsulfonylcarbamoyl)cyclopropylcarbamoyl)pyrrolidin-1-yl)-3,3-dimethyl-1-oxobutan-2-ylcarbamate (65 mg, 0.073 mmol, 73% yield) as a white foam. 1H NMR (400 MHz, MeOD) ppm 0.81-0.88 (m, 2 H) 1.07 (s, 9 H) 1.21-1.61 (m, 17 H) 1.64-1.80 (m, 1 H) 1.81-2.12 (m, 6 H) 2.37 (t, J=11.42 Hz, 1 H) 2.91-3.05 (m, 3 H) 3.91 (dd, J=10.29, 6.53 Hz, 1 H) 3.98 (d, J=11.04 Hz, 1 H) 4.48 (d, J=9.79 Hz, 1 H) 4.86-5.13 (m, 5 H) 5.66-6.14 (m, 3 H) 7.36 (t, J=7.28 Hz, 1 H) 7.45 (t, J=7.53 Hz, 2 H) 7.52-7.76 (m, 6 H). LC-MS (retention time: 3.39 min, Method B), MS m/z 885 (M+H).
