Reaktionsschritte
3-((E)-2-(Methyl((1R)-1-(methyl-((1R)-1-(methylcarbamoyl)-2-phenylethyl)-carbamoyl)-2-(2-naphthyl)ethyl)carbamoyl)vinyl)azetidine-1-carboxylic acid tert-butyl ester (0.45 g; 0.73 mmol) was dissolved in methylene chloride (2 mL). Trifluoroacetic acid (2 mL) was added and the reaction mixture was stirred for 7 min. Methylene chloride (50 mL), an aqueous solution of sodium hydrogen carbonate/sodium carbonate (50 mL; pH 9) and sodium carbonate were added to the reaction mixture until pH 8. The organic phase was dried (magnesium sulfate) and evaporated in vacuo to afford 0.29 g of the title compound.
