実験手順
To 69 mg (0.21 mmol) of 2-{3-[2-(1H-imidazol-4-yl)ethyl]ureido}-3-(4-methoxyphenyl)-propanoic acid (cf. preparation 2-3) dissolved in 2 mL of DMF is added a solution of 71 mg (0.20 mmol) of 4-butoxy-4-cyclohexylpiperidine trifluoroacetate in 1.5 mL of DMF, 44 mg (0.23 mmol) of EDC and 33 mg (0.24 mmol) of HOBt. After 2 hours 30 minutes, the reaction medium is hydrolysed with aqueous 2% citric acid solution and then extracted with dichloromethane. The organic phase is then washed with aqueous 1N sodium hydroxide solution. The organic phase is dried over MgSO4, filtered and concentrated. This oil is chromatographed on silica gel (eluent: 8/2 DCM/MeOH). 25 mg of 1-[2-(4-butoxy-4-cyclohexylpiperidin-1-yl)-1-(4-methoxy-benzyl)-2-oxoethyl]-3-[2-(1H-imidazol-4-yl)ethyl]urea are obtained in a yield of 22%.
