Article abstract of DOI:10.1007/BF01169245

Reductive cyclization of 1-(2,4-dinitrophenyl)-3-methyl-4-dimethylphenylsilylpyridinium chloride by the action of phenylhydrazine or hydrogen in the presence of Pd/C gave, for the first time, 7-nitro(amino)-3-dimethylphenylsilylpyrido[1,2-a]benzimidazoles. 1996 Plenum Publishing Corporation.
