실험 절차

HATU (11.61 g, 30.5 mmol) was added to a 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), and triethylamine (14.19 mL, 102 mmol) in DCM (220 mL) and was stirred at RT for overnight. The reaction was washed with 1N HCl (3×) and then 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).
