The synthesis of [11C]L-deprenyl-D2 for imaging of astrocytosis with positron emission tomography (PET) in neurodegenerative diseases has been previously reported.[ 11C]L-deprenyl-D2 radiosynthesis requires a precursor, L-nordeprenyl-D2, which has been previously synthesized from L-amphetamine as starting material with low overall yields. Here, we present an efficient synthesis of L-nordeprenyl-D2 organic precursor as free base and automated radiosynthesis of [11C]L-deprenyl-D2 for PET imaging of astrocytosis. The L-nordeprenyl-D2 precursor was synthesized from the easily commercial available and cheap reagent L-phenylalanine in five steps. Next, N-alkylation of L-nordeprenyl-D2 free base with [11C]MeOTf was optimized using the automated commercial platform GE TRACERlab® FX C Pro.
