formed, resulting in rearranged 1,4-diazepanes and piperazines as side products. 1,2-anellated piperazines 15, 18 and 19 were prepared by hydrogenation of the alpha,beta-unsaturated ester 13 and by condensation of the primaryamine 16b with formaldehyde, respectively. Receptor binding studies with radioligands revealed that the phenylacetamide 17b interacts with moderate affinity (K(i) = 181 nM) and considerable
