Process for preparing 1,4,7,10-tetraazacyclododecane and its derivatives |
| abstract |
een se t? t is prepared by the substitution of alkyl-substituted cyclene derivatives by cyclotetramerization of alkyl-substituted benzylaziridine derivatives, where benzylaziridine is prepared by in situ preparation of the alkyl-substituted benzylethanolamine derivative by reaction with acidic monitoring the reaction of the corresponding acid ester to the aqueous lye, without isolating the benzylaziridine derivative at 0.25 and 0.35 moles of strong acid per mole of benzylaziridine derivative, this being tetramerized to the tetrabenzylcycline derivative and then catalytic hydrogenation of benzyl group. |
