Summary: | The invention relates to a method for producing precursors for L-3,4-dihydroxy-6-[18F]fluorophenylalanine and 2-[18F]fluoro-L-tyrosine and the a-methylated derivatives thereof, said precursor, and a method for producing L-3,4-dihydroxy-6-[18F]fluorophenylalanine and 2-[18F]fluoro-L-tyrosine and the a-methylated derivatives thereof from the precursor. According to the invention, a compound of formula (3) is used to enable an automated synthesis of L-3,4-dihydroxy-6-[18F]fluorophenylalanine and 2-[18F]fluoro-L-tyrosine. The enantiomer purity of the product amounts to = 98%. |
