Versuchsvorschrift

(2E)-5-(tert-Butyloxycarbonylamino)-5-methylhex-2-enoic acid (0;19 g; 0.78 mmol) was dissolved in methylene chloride (10 mL). 1-Hydroxy-7-azabenzotriazole (0.11 g; 0.78 mmol) and N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide (0.16 g; 0.86 mmol) were added. The reaction mixture was stirred for 15 min at room temperature. 3-(Benzo[b]thiophen-3-yl)-N-methyl-2-methylamino-N-((1R)-1-methylcarbamoyl-2-phenylethyl)propionamide (0.32 g ; 0.78 mmol) was dissolved in methylene chloride (10 mL) and added. Diisopropylethylamine (0.13 mL; 0.78 mmol) was added. The reaction mixture was stirred for 12 hours at room temperature. Methylene chloride (10 mL) was added. The reaction was washed with water (20 mL), an aqueous solution of sodium hydrogen sulfate (10%; 20 mL), an aqueous solution of sodium hydrogen carbonate (saturated; 20 mL) and dried (magnesium sulfate). The solvent was removed in vacuo and the residue was chromatographed on silica (2×20 cm) using ethylacatate/methylene chloride (1:1) as eluent to afford 0.26 g of ((3E)-4-(((1R)-2-(benzo[b]thiophen-3-yl)-1-(methyl-(1-methylcarbamoyl-2-phenylethyl)carbamoyl)ethyl)methylcarbamoyl)-1,1-dimethylbut-3-enyl)carbamic acid tert-butylester.
