cyclocondensation reaction of simple ortho-phenylenediamine, formaldehyde and alcohols in presence of indium oxide nanoparticles as catalyst. The alcohol acts as reactant as well as solvent in this reaction. No other solvents or additives have been used for this reaction. The catalyst can be reused several times without significant loss of catalytic activity. A probable reaction mechanism has been
