Procedure

Step 1 (D): (2R,4R)-tert-butyl 2-((1S,2S)-1-(tert-butyldimethylsilyloxy)-3-(3,5-difluorophenyl)-2-(3-((R)-2-(methoxymethyl)pyrrolidine-1-carbonyl)benzamido)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), 50 mg, 0.074 mmol) in dichloromethane (2 mL) and DMF (5 mL) was added Hunig's base (28 mg, 0.222 mmol) to make a clear solution and HATU (36 mg, 0.0962 mmol) was then added. After stirring for 20 min, the reaction mixture was added (R)-2-(methoxymethyl)pyrrolidine (17 mg, 0.148 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 45 mg of the title compound (79% yield): 1H NMR (CDCl3, 500 MHz) δ 0.02 (3H, s), 0.05 (3H, s), 0.83 (9H, s), 0.86-0.89 (3H, m), 1.48-1.51 (11H, m), 1.72 (1H, m), 1.91-2.07 (4H, m), 2.18 (1H, d, J=15 Hz), 2.64 (1H, dd, J=10, 15 Hz), 2.90-2.94 (1H, m), 3.02 (1H, brd s), 3.28-3.38 (6H, m), 3.48 (1H, m), 3.55 (1H, m), 3.67 (1H, m), 3.74 (1H, m), 3.98 (1H, m), 4.04-4.12 (2H, m), 4.42 (1H, m), 4.59 (1H, m), 6.57-6.60 (1H, m), 6.76 (2H, d, J=5 Hz), 7.41-7.44 (1H, m), 7.60-7.62 (1H, m), 7.88 (1H, d, J=5 Hz), 7.96 (1H, s), 8.08 (1H, brd s).
