N-(__ampersandsignalpha;-cyano-__ampersandsignalpha;-substituted phenyl)-methylanilines (I) on exposure to bright sunlight using soda glass photoreactor are transformed smoothly, with insertion of one methylene group from the solvent (methanol), into substituted benzoimidazoloquinolines (II) with improved yields under benzophenone sensitized conditions employing basic aqueous alcoholic medium in the presence of iodide salt. These compounds have been characterized through their, elemental analysis, IR, 1H NMR, 13C NMR and mass spectral studies.
