and 5-7 were prepared from 3-amino-beta-carboline (8) in one step via diazotization, followed by reaction with the appropriate nucleophile in order to determine their binding affinity for benzodiazepinereceptors (BzR). All three of the 3-alkoxy-beta-carbolines 2 (IC50 = 124 nM), 3 (IC50 = 24 nM), and 4 (IC50 = 11 nM) have high affinities for BzR. The beta-carbolines substituted with electron-withdrawing
