実験手順
To 189 mg (0.57 mmol) of 2-{3-[2-(1H-imidazol-4-yl)ethyl]ureido}-3-(4-methoxy-phenyl)propanoic acid (cf. preparation 2-3) dissolved in 3.5 mL of dichloromethane and 1.0 mL of dimethylformamide are added 0.2 mL (1.14 mmol) of diisopropylethylamine, 202 mg (0.63 mmol) of TBTU and 95 mg (0.57 mmol) of 3-cyclohexanecarbonylazetidine. After 5 hours, the solution is washed with 1N sodium hydroxide solution and the organic products are extracted with dichloromethane. The organic phase is dried over magnesium sulfate, filtered and concentrated. The crude product obtained is purified by preparative TLC (9/1 dichloromethane/methanol). 8.5 mg of 1-[2-(3-cyclohexanecarbonylazetidin-1-yl)-1-(4-methoxybenzyl)-2-oxoethyl]-3-[2-(1H-imidazol-4-yl)ethyl]urea are obtained in a yield of 3%.
