A synthesis of 2-deoxy-2-{18F}fluoro-D-glucose using accelerator-produced 18F-fluoride ion generated in a water target

Abstract
A synthesis of 2-deoxy-2-{18F}fluoro-D-glucose (2-{18F}DFG) [used in the measurement of regional cerebral glucose metabolism] from 1,2-anhydro-3,4:5,6-di-O-isopropylidene-1-C-nitro-D-mannitol was developed. The procedure employed 18F produced by the 16O(3He,p)18F reaction using a water target. The label was introduced using KH{18F}F2 dried by microwave heating; the 18F-labeled derivative, upon treatment with 80% trifluoroacetic acid, afforded 2-{18F}DFG in a radiochemical yield of 10%. The total time of the synthesis was less than 110 min.
