A new chemical route for the preparation of 2-(/sup 18/F)fluoro-2-deoxy-D-glucose (2-/sup 18/FDG) is discussed using anhydrous (/sup 18/F)fluoride produced by the /sup 20/Ne(d,..cap alpha..)/sup 18/F reaction. The anhydous /sup 18/F/sup -/ is reacted with a previously prepared precursor, methyl 4,6-o-benzylidene-3-o-methyl-2-O-trifluoromethanesulfonyl-..beta..-D-mannopyranoside, in dimethyl formamide or hexamethylophosphoric triamide. The corresponding fluoro-deoxy-glucose derivative, upon treatment with borontribromide or concentrated hydrochloric acid, yields 2-/sup 18/FDG in 10% (overall) yield. The substrate was characterized by thin-layer chromatography (TLC), and high-performance liquid chromatography (HPLC). Biodistribution studies were performed in mice, and imaging studies in dogs.
