Versuchsvorschrift

3-((E)-2-Carboxyvinyl)azetidine-1-carboxylic acid tert-butyl ester (0.28 g; 1.24 mmol) was dissolved in methylene chloride (3 mL). 1-Hydroxy-7-azabenzotriazole (0.17 g; 1.24 mmol) and N-(3-dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (0.26 g; 1.36 mmol) were added and the reaction mixture was stirred for 15 min at room temperature. N-Methyl-2-methylamino-N-(1-(methyl-carbamoyl)-2-phenylethyl)-3-(2-naphthyl)propionamide (0.50 g; 1.24 mmol) (prepared as in example 1) was dissolved in methylene chloride (3 mL) and added to the reaction mixture. Ethyldiisopropylamine (0.21 mL; 1.24 mmol) was added and the reaction mixture was stirred for 12 hours at room temperature. Methylene chloride (20 mL) was added and the reaction mixture was washed with water (10 mL), an aqueous solution of sodium hydrogen sulfate (10 mL; 10%), an aqueous solution of sodium hydrogen carbonate (10 mL; sat.) and water (10 mL). The organic phase was dried (magnesium sulfate) and evaporated in vacuo. The residue was chromatographed on silica (2,5×20 cm) using 2.5%(7% ammonia in ethanol) in methylene chloride as eluent to afford 0.49 g of 3-((E)-2-(methyl((1R)-1-(methyl((1R)-1-(methylcarbamoyl)-2-phenylethyl)carbamoyl)-2-(2-naphthyl)ethyl)carbamoyl)vinyl)azetidine-1-carboxylic acid tert-butyl ester.
