Method and precursor for production of no-carrier-added N-(4-[18F] fluorobutyl)-Ethacrynic amide

The present invention is related to a precursor for no-carrier-added fluorine-18 labeled ethacrynic acid, N-(4-[18F]fluorobutyl)-Ethacrynic amide([18F]FBuEA) and the preparation method for HPLC non-radioactive standards. Its chemical structure is shown in the following: In the precursor, R1 represen...

Beschreibung
Zusammenfassung:	The present invention is related to a precursor for no-carrier-added fluorine-18 labeled ethacrynic acid, N-(4-[18F]fluorobutyl)-Ethacrynic amide([18F]FBuEA) and the preparation method for HPLC non-radioactive standards. Its chemical structure is shown in the following: In the precursor, R1 represents a protective group for the amide functional group; R2 represents leaving group; or R1 represents carboxyl group, R2 represents p-tosyloxy, methane sulfonyloxy group or trifluoromethane sulfonyloxy group or bromine (Br). For the HPLC non-radioactive standards, R1 represents a protective group for the amide functional group and hydrogen, R2 represents fluorine.
