5-benzoylbenzimidazoles has been developed. A benzylcyanide functional group was linked to 2% divinylbenzene cross-linked polystyrene through a dimethylsilyl linker. Coupling with 5-chloro-2-nitroaniline followed by oxidativedecyanation gave benzophenone 11 as a key intermediate in an efficient one-pot reaction procedure. After reduction of the nitro group and oxidative cyclization with a variety of aldehydes
