Procedure

HATU (11.61 g, 30.5 mmol) was added to a DCM (220 mL) solution of (2S,4R)-1-((2S,3R)-2-((tert-butoxycarbonyl)amino)-3,5-dimethylnon-8-enoyl)-4-hydroxypyrrolidine-2-carboxylic acid (10.50 g, 25.5 mmol), (1R,2S)-1-amino-N-((1-(fluoromethyl)cyclopropyl)sulfonyl)-2-vinylcyclopropanecarboxamide HCl (8.37 g, 28 mmol), triethylamine (14.19 mL, 102 mmol). The reaction mixture was stirred at RT for overnight. The reaction was washed with 1N HCl (3×) and then with brine and evaporated on rotovap. The crude material was purified by silica gel chromatography using 20-40% Acetone in hexanes. The product fractions were collected and the solvent removed under vacuum to give the desired product tert-butyl((2S,3R)-1-((2S,4R)-2-(((1R,2S)-1-(((1-(fluoromethyl)cyclopropyl)sulfonyl)carbamoyl)-2-vinylcyclopropyl)carbamoyl)-4-hydroxypyrrolidin-1-yl)-3,5-dimethyl-1-oxonon-8-en-2-yl)carbamate (15 g, 90% yield). MS: MS m/z 657.3 (M++1).
