실험 절차
200 ml of absolute ethanol is poured over 8.61 g (20 mmol) of N,N',N"-tris-(ethoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane (produced according to DE 36 25 417 A1) in a bomb tube. After 4.15 g (20 mmol) of N-butyl-N-[(2-oxiranyl)-methyl]-methanesulfonic acid amide is added (Example 2a), the bomb tube is closed, flushed with nitrogen, and the resulting reaction mixture is heated for 16 hours to 90° C. After the reaction (TLC control) is completed, the solvent is evaporated in a vacuum and the yellowish, oily residue is chromatographed on silica gel (eluent: chloroform/methanol; methanol: 0-80%).
