We have prepared azabicyclo [3.2. 1] derivatives (C-3-substituted tropanes) that bind with high affinity to the dopamine transporter and inhibit dopamine reuptake. Within the series, 3- {2-[bis-(4-fluorophenyl) methoxy] ethylidene}-8-methyl-8-azabicyclo [3.2. 1] octane (8) was found to have the highest affinity and selectivity for the dopamine transporter. These azabicyclo [3.2. 1](bridged piperidine) series of compounds differ from the well-known ...
