Alkylation of potassium phthalimide (I) with an excess of 1,8-dibromooctane (II) in refluxing acetone afforded N-(8-bromooctyl)phthalimide (III). This was condensed with 6-O-demethylgalanthamine (IV) in the presence of Et3N in boiling acetonitrile to give phthalimidooctyl compound (V). Finally, reaction with N-bromosuccinimide in the presence of azobisisobutyronitrile provided the iminium bromide.
