Abstract
[carbonyl‐^11^C]Benzyl acetate ([^11^C]1) has been proposed as a potential agent for imaging glial metabolism of acetate to glutamate and glutamine with positron emission tomography. [^11^C]1 was synthesized from [^11^C]carbon monoxide, iodomethane and benzyl alcohol via palladium‐mediated chemistry. The radiosynthesis was automated with a modified Synthia platform controlled with in‐house developed Labview software. Under production conditions, [^11^C]1 was obtained in 10% (n=6) decay‐corrected radiochemical yield from [^11^C]carbon monoxide in >96% radiochemical purity and with an average specific radioactivity of 2415 mCi/µmol. The total radiosynthesis time was about 45 min. Peak uptake of radioactivity in monkey brain (SUV=3.1) was relatively high and may be amenable to measuring uptake and metabolism of acetate in glial cells of the brain.
