실험 절차

100 mg (0.51 mmol) of N-cyclopropyl-N-piperidin-4-ylpropionamide, 170 mg (0.51 mmol) of 2-{3-[2-(1H-imidazol-4-yl)ethyl]ureido}-3-(4-methoxyphenyl)propanoic acid (cf. preparation 2-3), 108 mg (0.56 mmol) of EDC and 76 mg (0.56 mmol) of HOBT are dissolved in 5 mL of DMF under nitrogen. The mixture is stirred at room temperature overnight, and the solution is then washed with aqueous 5% citric acid solution and extracted with ethyl acetate. The organic phase is washed with aqueous 1N NaOH solution and then dried and evaporated. The crude product obtained is purified by preparative HPLC (conditions cf. page 38). 2 mg of N-cyclopropyl-N-{1-[2-{3-[2-(1H-imidazol-4-yl)ethyl]ureido}-3-(4-methoxyphenyl)propionyl]piperidin-4-yl}-propionamide are obtained in a yield of 8%.
