GT-2331 is a potent histamine H3 antagonist which has entered clinical trials. Efficient multigram syntheses of this compound and its enantiomer are described. The literature reports that GT-2331 is the dextrorotatory (+), more potent, enantiomer of 4-[2-(5,5-dimethylhex-1-ynyl)cyclopropyl]-1H-imidazole with the absoluteconfiguration of (1R,2R)-1. However, we found that the dextrorotatory, more potent
