Versuchsvorschrift

HATU (248 mg, 0.652 mmol) was added to a solution of, (2S,4R)-methyl 4-methoxy-4-(2′-vinylbiphenyl-4-yl)pyrrolidine-2-carboxylate (200 mg, 0.593 mmol), (S)-2-((2,2-dimethylpent-4-enyloxy)carbonylamino)-3,3-dimethylbutanoic acid (201 mg, 0.741 mmol) and DIEA (0.311 mL, 1.778 mmol) in DCM (8 mL) and stirred at r.t. 60 hours. The reaction was evaporated and purified on the Biotage (10-40% EtOAc:Hex) to give (2S,4R)-methyl 1-((S)-2-((2,2-dimethylpent-4-enyloxy)carbonylamino)-3,3-dimethylbutanoyl)-4-methoxy-4-(2′-vinylbiphenyl-4-yl)pyrrolidine-2-carboxylate (235 mg, 0.398 mmol, 67% yield) as white solid. 1H NMR (400 MHz, CHLOROFORM-d) δ ppm 0.83-0.94 (m, 6H) 0.97-1.02 (m, 1H) 1.06-1.10 (m, 1H) 1.12-1.19 (m, 7H) 1.95-2.07 (m, 2H) 2.46-2.59 (m, 1H) 2.88 (d, J=12.80 Hz, 1H) 2.92-3.03 (m, 3H) 3.65-3.74 (m, 1H) 3.74-3.79 (m, 3H) 3.79-3.86 (m, 1H) 4.00-4.09 (m, 1H) 4.14-4.21 (m, 1H) 4.31-4.42 (m, 1H) 4.85-4.92 (m, 1H) 4.95-5.09 (m, 2H) 5.17-5.26 (m, 1H) 5.38-5.49 (m, 1H) 5.67-5.84 (m, 2H) 6.60-6.75 (m, 1H) 7.25-7.30 (m, 1H) 7.30-7.42 (m, 6H) 7.61-7.68 (m, 1H).
