Procedure

To an iced slurry of (2S,4R)-4-(biphenyl-4-yl)-1-((S)-2-(tert-butoxycarbonylamino)-3,3-dimethylbutanoyl)-4-(butylthio)pyrrolidine-2-carboxylic acid (60 mg, 0.105 mmol), (1R,2S)-1-amino-N-(cyclopropylsulfonyl)-2-vinylcyclopropanecarboxamide, p-toluenesulfonate salt, H2O (53.1 mg, 0.127 mmol), and HATU (60.1 mg, 0.158 mmol) in DCM (2 mL) was added N,N-diisopropylethylamine (0.055 mL, 0.316 mmol). The formed colorless slurry was stirred at room temperature for 5 h (it became light yellow solution). Diluted with DCM, quenched with 5% citric acid. The separated organic layer was washed with sat. sodium citrate and brine, dried over MgSO4, filtered, evaporated in vacuo. The residue was purified by BIOTAGE® column, eluted with gradient 5%-40% acetone-hexane to yield the desired product tert-butyl (S)-1-((2S,4R)-4-(biphenyl-4-yl)-4-(butylthio)-2-((1R,2S)-1-(cyclopropylsulfonylcarbamoyl)-2-vinylcyclopropylcarbamoyl)pyrrolidin-1-yl)-3,3-dimethyl-1-oxobutan-2-ylcarbamate (69 mg, 0.082 mmol, 78% yield) as a white solid. 1H NMR (500 MHz, MeOD) ppm 0.83 (t, J=7.32 Hz, 3H), 1.03-1.12 (m, 10H), 1.19-1.36 (m, 4H), 1.35-1.49 (m, 4H), 1.48 (s, 9H), 1.88 (s, J=7.93, 5.49 Hz, 3H), 2.14-2.24 (m, 1H), 2.23-2.30 (m, 1H), 2.35 (t, J=11.60 Hz, 1H), 2.39-2.53 (m, 1H), 2.76-2.87 (m, 1H), 2.89-3.00 (m, 1H), 3.93 (dd, J=10.68, 641 Hz, 1H), 3.99 (d, J=10.99 Hz, 1H), 4.51 (d, J=10.07 Hz, 1H), 5.06 (d, J=10.99 Hz, 1H), 5.10-5.19 (m, 1H), 5.29 (d, J=17.09 Hz, 1H), 5.69-5.83 (m, 1H), 7.37 (t, J=7.32 Hz, 1H), 7.46 (t, J=7.78 Hz, 2H), 7.55-7.63 (m, 4H) 7.64-7.77 (m, 2H).
