| titleOfInvention | Method for producing tetraazacycloalkane |
| abstract | The present invention relates to a process for preparing macrocyclic tetraazacycloalkane having 12 to 16 ring elements, the process comprising the steps of: (i) reacting a tetraazaalkane with a bridging agent to form a tetraazaalkane of four amine nitrogen Preparing a tricyclic fused intermediate by coupling an atom with a bridge-former; (ii) reacting said intermediate to de-couple an alkandiylidene bridge-former from tertiary amine nitrogen atoms at the ring-fusing site of said tri-cyclic fusing intermediate to form a Introducing an alkylene bridge between the secondary amine nitrogen atoms; And (iii) de-coupling as needed the bridge-former to produce the macrocyclic tetraazacycloalkane. |
