2-(2′-phenylimidazo[1,2-a]pyridin-3′-yl)acetate
are reported. The ability of these compounds to displace
[3H]diazepam from central and mitochondrial
(peripheral-type) benzodiazepine receptors has been examined. Ethyl

acetate (21) was selective for peripheral-type receptors
(IC5013 nM) but none bound strongly to central
receptors.
