Versuchsvorschrift

0.87 g of methyl (R)-{2-[N-{1-[(2,6-dimethoxy-4-methylphenyl)pentylcarbamoyl]-5-aminopentyl}carbamoyl]indol-1-yl}acetate, 0.645 g of BOP and 0.23 g of cinnamic acid are successively added to 30 ml of dimethylformamide. After cooling to -5° C., 0.26 g of N-ethylmorpholine is added under an inert atmosphere and the reaction mixture is maintained at 0° C. for 2 hours and is then left at room temperature for 18 hours. The reaction mixture is poured into a large volume of water and extraction is carried out with ethyl acetate. The organic extracts are dried over anhydrous sodium sulphate and evaporated to dryness. The residual oil is purified by flash chromatography on silica gel, eluent: CH2Cl2 /CH3OH 97/3 (v/v) in order to obtain methyl (R)-{2-[N-{1-[(2,6-dimethoxy-4-methylphenyl)pentylcarbamoyl]-5-(cinnamoylamino)pentyl}carbamoyl]indol-1-yl}acetate in the form of an oil.
