(1,1-Dimethyl-2-((N-methyl-N-((1R)-1-(N-methyl-N-((1R)-1-(methylcarbamoyl)-2-phenylethyl)carbamoyl)-2-(1-naphthyl)-ethyl)carbamoyl)methoxy)ethyl)carbamic acid tert-butylester (0.26 g; 0.41 mmol) was dissolved in methylene chloride (3 mL) and trifluoroacetic acid (2 mL) was added. The reaction mixture was stirred for 5 min at room temperature. Methylene chloride (5 mL), an aqueous solution of sodium hydrogen carbonate (saturated) and sodium hydrogen carbonate (solid) were added until pH 8. The aqueous phase was extrated with methylene chloride (3×15 mL) and the combined organic layers were dried (magnesium sulfate). The solvent was removed in vacuo to afford 0.25 g of the title compound.
