실험 절차

(2E)-5-(tert-Butoxycarbonylamino)-5-methylhex-2-enoic acid (0.344 g; 1.41 mmol) was dissolved in methylene chloride (10 mL). 1-Hydroxy-7-azabenzotriazole (0.19 g; 1.41 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (0.298 g; 1.56 mmol) were added. The reaction mixture was stirred for 15 min at room temperature. (2R)-N-Methyl-2-methylamino-3-(1-naphthyl)-N-((1R)-2-phenyl-1-(((tetrahydrofuran-2-yl)methyl)carbamoyl)ethyl)-propionamide (0.67 g; 1.42 mmol) was dissolved in methylene chloride (10 mL) and added. Diisopropyletylamine (0.242 mL; 1.41 mmol) was added. The reaction mixture was stirred for 12 hours at room temperature. Methylene chloride (20 mL) was added. The reaction mixture as washed with water (30 mL), an aqueous solution of sodium hydrogen sulfate (10%;30 mL), an aqueous solution of sodium hydrogen carbonate (pH 8; 30 mL) and dried (magnesium sulfate). The solvent was removed in vacuo and the residue was chromatographed on silica (3×30 cm) using methylene chloride/ethyl acetat (1:1) as eluent to afford 0.81 g of ((3E)-1,1-dimethyl-4-(methyl-((1R)-1-(methyl-((1R)-2-phenyl-1-(((tetrahydrofuran-2-yl)methyl)carbamoyl)ethyl)carbamoyl)-2(1-naphtyl)ethyl)-carbamoyl)but-3-enyl)carbamic acid tert butylester.
