## Abstract As potential P.E.T. imaging agents for the benzodiazepine receptor, two fluorine‐ 18 labeled analogues of the β‐carbolines were prepared __via__ N‐ alkylation of the corresponding desbenzyl amine precursors with [^18^F]fluorobenzyl iodide.

✦ Synopsis
Numerous 0-carboline-3-carboxamides were synthesized by amidation of p-carboline-3-carboxylic acid, with various amino acids and amino acid esters serving as arnine components, and tested in respect to their affinity for the benzodiazepine receptor in mouse brain membranes. The title compounds have affinities in the low micromolar range. The results are discussed with respect to their relevance for a possible p-carboline structure containing the endogenous ligand of the benzodiazepine receptor.
