Versuchsvorschrift

Step 2 (A): (2R,4R)-tert-butyl 2-((1S,2S)-1-(tert-butyldimethylsilyloxy)-2-(3-(carbamoyl)benzamido)-3-(3,5-difluorophenyl)propyl)-4-propoxypyrrolidine-1-carboxylate. To a solution of 3-(((1S,2S)-1-((2R,4R)-1-(tert-butoxycarbonyl)-4-propoxypyrrolidin-2-yl)-1-(tert-butyldimethylsilyloxy)-3-(3,5-difluorophenyl)propan-2-yl)carbamoyl)benzoic acid (Step 1 (C), 60 mg, 0.088 mmol) in dichloromethane (2 mL) was added Hunig's base (34 mg, 0.267 mmol) to make a clear solution and HATU (45 mg, 0.12 mmol) was then added. After stirring for 20 min, the reaction mixture was added N-methylpropan-1-amine (13 mg, 0.178 mmol) and the reaction mixture was stirred at rt overnight. Ethyl acetate (100 mL) was added and the mixture was washed with Brine, H2O, dried and concentrated to give 55 mg of the title compound (85% yield): 1H NMR (CDCl3, 500 MHz) δ 0.02 (3H, s), 0.05 (3H, s), 0.71-0.76 (1H, m), 0.83 (9H, s), 0.87 (3H, m), 0.91-1.00 (2H, m), 1.40-1.53 (12H, m), 1.60-1.67 (1H, m), 2.01-2.05 (1H, m), 2.17-2.20 (1H, m), 2.64 (1H, m), 2.89-3.04 (4H, m), 3.17 (1H, brd s), 3.27-3.36 (3H, m), 3.48 (1H, brd s), 3.74 (1H, m), 3.97 (1H, m), 4.04-4.11 (2H, m), 4.58 (1H, m), 6.58 (1H, m), 6.76 (2H, d, J=5 Hz), 7.41-7.48 (2H, m), 7.86 (2H, s), 8.13 (1H, brd s).
