A convergent strategy was followed to modify systematically carbazole based CB2 receptor ligands. The length of the N-(fluoroalkyl) group (n in 7), the length of the alkanamide (m in 7) and the substitution pattern of the phenyl moiety (X and Y in 7) were varied systematically. The highest CB 2 affinity was found for the 2-fluoroethyl substituted carbazole derivative 20a (Ki = 5.8 nM) containing the propionamide and the 2-bromo-4-fluorophenyl moiety. According to docking studies 20a fits nicely into the binding pocket of the CB2 receptor, but elongation of the fluoroethyl side chain leads to a different binding mode of the ligands. The high CB2 affinity together with the high selectivity over the CB 2 subtype qualifies the fluoroethyl derivative 20a to be developed as a PET tracer.

An efficient and facile synthesis of six new 1,2,4-oxadiazoles (6a-f) with a tertiary amide group attached on the side-chain, in high yield, is described. Correct assignments of side-chain methylene, methyl protons, and carbon signals have been made with the assistance of COSY, NOESY and HETCOR NMR experiments.
