چکیده
The title compound, C(24)H(21)N(3)O, was prepared by the reaction of (Z)-2-(1H-indol-3-ylmethyl-ene)-1-aza-bicyclo-[2.2.2]octan-3-one with α-bromo-p-toluonitrile, under phase-transfer catalytic (PTC) conditions using triethyl-benzyl-ammonium chloride and 50% w/v aqueous NaOH solution in dichloro-methane. The crystal structure indicates the presence of a double bond with Z geometry connecting the aza-bicyclic and indole groups.
