実験手順
0.14 g (0.38 mmol) of methyl(S)-3-(4-methoxyphenyl)-2-(4-nitrophenoxycarbonyl-amino)propionate is diluted in 2 mL of DMF. The solution is heated to 80° C. and 0.16 g (0.76 mmol) of ethyl[2-(1H-imidazol-4-yl)ethyl]amine hydrochloride and 0.13 mL (1.3 mmol) of diisopropylethylamine are then added. After 5 minutes, the reaction medium is cooled to room temperature and stirred for 15 minutes. Toluene is added and the solvents are evaporated off. The crude product obtained is chromatographed on silica gel (eluent: 8/2 dichloromethane/methanol). 0.15 g of methyl(S)-2-{3-ethyl-3-[2-(1H-imidazol-4-yl)ethyl]ureido}-3-(4-methoxyphenyl)-propionate in the form of a colourless oil is obtained in a yield of 100%.
