Procedure

Methyl-((1R)-1-(methyl-((1R)-2-phenyl-1-(((tetrahydrofuran-2-yl)methyl)carbamoyl)ethyl)carbamoyl)-2-(1-naphtyl)ethyl)carbamic acid tert butylester (0.84 g; 1.46 mmol) was dissolved in methylene chloride (3 mL) and trifluoroacetic acid (2 mL) was added. The reaction mixture was stirred for 5 min at roomtemperature. Water (3 mL) and methylene chloride (5 mL) was added. Sodium hydrogen carbonate (solid) was added until pH 8. The reaction mixture was extracted with methylene chloride (3×10 mL). The combined organic layers were dried (magnesium sulfate) and evaporated in vacuo to afford 0.68 9 of (2R)-N-methyl-2-methylamino-3-(1-naphtyl)-N-((1R)-2-phenyl-1-((tetrahydrofuran-2-yl-methyl)-carbamoyl)ethyl)propionamide.
