The synthesis of the [ 3 H] labelled peripheral benzodiazepine receptor (PBR) ligand CB 34, useful for binding assay, tissue distribution studies, and elucidation of the physiological role of PBR, is described. Catalytic reduction with 3 H 2 gas and 10% Pd/C catalyst of the key intermediate 2 afforded the product at a specific activity of 111 Ci/mmol. Copyright © 2001 John Wiley & Sons, Ltd.
