Abstract:
A method for preparing a NOTA derivative is revealed. The method includes a plurality of steps. First take 4-toluenesulfonyl chloride and diethylenetriamine to carry out tosylation reaction and obtain a first product. Then the first substitution reaction takes place upon addition of the first product with sodium methoxide to get the second product. Next take 4-toluenesulfonyl chloride to react with ethylene glycol for preparing a third product by tosylation reaction therebewteen. Then a coupling reaction between the third product and the second product is carried out to produce a fourth product. The second substitution reaction occurs involving the fourth product in the presence of sulfuric acid. Lastly take the reaction product and hydrochloric acid to have bonding reaction and obtain a final product. The method solves the water-absorption problem of the cyclic organic compound TACN, a NOTA derivative.

Claim (Index 7):
The method as claimed in  claim 1 , wherein the reaction product is 1,4,7-Triazacyclononane (TACN).
