Reaktionsschritte

HATU (11.54 g, 30.4 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 (10.44 g, 25.3 mmol), (1R,2S)-1-amino-N-(cyclopropylsulfonyl)-2-vinylcyclopropanecarboxamide, p-toluenesulfonate salt (11.17 g, 27.8 mmol), and Hunig's Base (17.67 ml, 101 mmol) in DCM (200 ml) and was stirred at RT for overnight. The reaction was washed with 1N HCl (3×) and then brine and evaporated on rotovap, and purified to get the final product tert-butyl ((2S,3R)-1-((2S,4R)-2-(((1R,2S)-1-((cyclopropylsulfonyl)carbamoyl)-2-vinylcyclopropyl)carbamoyl)-4-hydroxypyrrolidin-1-yl)-3,5-dimethyl-1-oxonon-8-en-2-yl)carbamate (14.8 g, 23.69 mmol, 94% yield) as a light orange foam.
