실험 절차

To 57 mg (0.17 mmol) of 2-{3-[2-(1H-imidazol-4-yl)ethyl]ureido}-3-(4-methoxyphenyl)-propanoic acid (cf. preparation 2-3) dissolved in 4 mL of dichloromethane and 1.5 mL of dimethylformamide are added 0.12 mL (0.68 mmol) of diisopropylethylamine, 61 mg (0.19 mmol) of TBTU and 55 mg (0.17 mmol) of 3-butoxy-3-phenylazetidine trifluoroacetate. After 3 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 (eluent: 9/1 dichloromethane/methanol). 3 mg of 1-[2-(3-butoxy-3-phenylazetidin-1-yl)-1-(4-methoxybenzyl)-2-oxoethyl]-3-[2-(1H-imidazol-4-yl)ethyl]urea are obtained in a yield of 3%.
