実験手順

((1R)-2-(Benzo[b]thiophen-3-yl)-1-(methyl-((1R)-1-methylcarbamoyl-2-phenyl ethyl)carbamoyl)ethyl)-methylcarbamic acid tert-butylester (0.89 g; 1.70 mmol) was dissolved in methylene chloride (3 mL) and trifluoroacetic acid (2 mL) was added. is The reaction mixture was stirred for 45 min at room temperature. Water (5 mL) was added. Methylene chloride (5 mL), an aqueous solution of sodium hydrogen carbonate (saturated) and sodium hydrogen carbonate (solid) was added until pH 8. The aqueous phase was extracted with methylene chloride (3×10 mL). The combined organic phases were dried (magnesium sulfate) and evaporated in vacuo to afford 0.66 g of (2R)-3-(Benzo[b]thiophen-3-yl)-N-methyl-2-methylamino-N-((1R)-1-methylcarbamoyl-2-phenylethyl)propionamide.
